    ABSTRACT: A new linear elastic and perfectly brittle interface model for mixed mode is presented and analysed. In this model, the interface is represented by a continuous distribution of springs which simulates the presence of a thin elastic layer. The constitutive law for the continuous distribution of normal and tangential initially-linear-elastic springs takes into account possible frictionless elastic contact between adherents once a portion of the interface is broken. A perfectly brittle failure criterion is employed for the springs, which enables the study of crack onset and propagation. This interface failure criterion takes into account the variation of the interface fracture toughness with the fracture mode mixity. A unified way to represent several phenomenological both energy and stress based failure criteria is introduced. A proof relating the energy release rate and tractions at an interface point (not necessarily a crack tip point) is introduced for this interface model by adapting Irwin’s crack closure technique for the first time. The main advantages of the present interface model are its simplicity, robustness and computational efficiency, even in the presence of snap-back and snap-through instabilities, when the so-called sequentially linear (elastic) analysis is applied. This model is applied here in order to study crack onset and propagation at the fibre-matrix interface in a composite under tensile/compressive remote biaxial transverse loads. Firstly, this model is used to obtain analytical predictions about interface crack onset, while investigating a single fibre embedded in a matrix which is subjected to uniform remote transverse loads. Then, numerical results provided by a 2D boundary element analysis show that a fibre-matrix interface failure is initiated by the onset of a finite debond in the neighbourhood of the interface point where the failure criterion is first reached (under increasing proportional load); this debond further propagates along the interface in mixed mode or even, in some configurations, with the crack tip under compression. The analytical predictions of the debond onset position and associated critical load are used for several parametric studies of the influence of load biaxiality, fracture-mode sensitivity and brittleness number, and for checking the computational procedure implemented.

    ABSTRACT: The problem of an interface crack between a shape memory alloy and an elastic layer is numerically addressed. The shape memory alloy behavior is modeled with a continuum thermodynamics based constitutive model embedded within the finite element method. With the help of the boundary layer approach, and the assumption of small scale transformation zone, the K-dominated region in the tip of the interface crack is loaded under general mixed-mode condition. Both slow and fast loading rates are considered to study the effects of thermo-mechanical coupling on the interface crack tip fields, especially the crack tip energy release rate within a history-dependent J-integral framework, the stress/strain curve during the loading process, and the shape and size of the transformation zone and the heated zone. A special effort is made to investigate how changing the rate of applied loading, the mode-mixity, and the material properties of SMA and elastic layer modify the crack tip fields.

    ABSTRACT: This paper studies the dynamic characteristics of the debonding mechanism in beams strengthened with FRP. The paper formulates a special finite element for the dynamic analysis of the layered beam and looks into the parameters that govern the dynamic phenomenon. The finite element is based on an extended high order theory that incorporates a rich 2D elasticity based stress and displacement fields in the adhesive layer and allows to consider debonding at the two physical interfaces of that layer through cohesive interfaces. These concepts are combined with the basic form of inertial forces to formulate a multi-layered finite element that utilizes the versatility of the FE method and avoids the need to mesh through the thickness of each layer. The computational framework is then used to study the dynamic debonding process and to examine the impact of a series of geometrical, elastic, mechanical, and physical parameters. Among other findings, the investigation reveals the potentially negative impact of stiffening the FRP layer on the dynamic failure, the sensitivity to the properties of the adhesive, and the interesting insensitivity to the loading rate (within the examined range). Finally, the sensitivity of the response to the properties of the cohesive interfaces and the idea of characterizing those interfaces based on dynamic observations are discussed.

    ABSTRACT: The dynamic fragmentation of brittle rocks (slate, granite, marble and limestone) under low-velocity impact was investigated using freefall round hammer experiments. A three-parameter generalized extreme value distribution was used to characterize the fragment sizes, and the finest particles were neglected. A log10 transformation of fragment size was adopted to overcome the problem that the interval of adjacent fragments size increases as the fragment size grows. The results reveal that the frequency distributions and num-based cumulative frequency distributions based on number have a certain change law with variations in impact energy and hammer size; the frequency distribution curve became narrower, and the cumulative frequency distribution curve moved toward the left as the impact energy increased, and the hammer size decreased. Marble was most easily broken followed by granite, limestone and slate, which was proved by scanning electron microscope images of the fracture surfaces of the four rocks. Because fragmentation is a stochastic process, the equivalent diameters of the fragments always had a more obvious regularity than the major and minor axes in the histograms. Therefore, the mean value of the equivalent diameter was used as the experimental average fragment size. Comparing the experimental results with the theoretical results of average fragment sizes that were predicted by four normalized models, it was determined that Levy and Molinari’s model and Zhou et al.’s model better forecasted the fragment sizes.

    ABSTRACT: Brittle crack-arrest fracture toughness (KIa) was determined in low (1.5 kJ/mm) and high (53 kJ/mm) heat-input weld specimens with a large scale (1×1 m) and thickness (50 and 80 mm). An instant impact having energy of 2.7 kJ was imposed into the full-thickness notch tip at low temperature and initiates crack propagation toward a higher temperature region where the crack stopped due to the improved fracture toughness. The relationship between the toughness and crack-arrest temperature provides the KIa at -10∘C of about 2700 and 2200N/mm3/2 in the low and high heat-input weld specimens, respectively. This discrepancy was correlated to the grain size and Charpy impact energy of the notch region caused by the amounts of heat inputs in each weld specimen.

    ABSTRACT: In this paper, we derive the exact closed-form fundamental solutions due to uniform extended displacement discontinuities over a triangular element in a piezoelectric half-space. Using the triangular elements to partition the penny-shaped crack, the triangular element fundamental solutions are verified by comparing with the existing analytical solution associated with the penny-shaped crack. The polarization saturation model is then applied to an elliptical crack in the piezoelectric half-space, and the resulting nonlinear fracture problem is solved by combing the triangular element fundamental solutions and the displacement discontinuity method. The electric yielding zone and the extended field intensity factors are obtained by an iterative approach. The effects of the applied mechanical load and electric displacement, the polarization saturation in the yielding zone, and the aspect ratio of the elliptical crack on the yielding zone size and field intensity factors are discussed through numerical examples.

    ABSTRACT: In this paper, the influences of the induced Coulomb tractions on the static and dynamic crack-tip fracture parameters of semi-permeable piezoelectric cracks are studied and discussed. The static crack problems are solved by a static dual boundary element method (BEM), while the corresponding crack problems under dynamic impact loading are numerically analyzed by a time-domain BEM considering the inertial effects. In the numerical implementation, a collocation method is applied for the spatial discretization together with a quadrature formula for the temporal discretization. An iterative scheme based on the quasi-Newton method is adopted to solve the corresponding non-linear boundary-value problem resulted from the semi-permeable electric boundary conditions and the induced Coulomb tractions on the crack-faces. The crack-tip facture parameters involving the field intensity factors, the energy release rate and the mechanical strain energy release rate are evaluated by a displacement extrapolation method. Some examples are presented to compare the effects of the Coulomb tractions on the static and dynamic fracture parameters.

    ABSTRACT: In this paper, a polygonal finite element method is presented for crack growth simulation with minimum remeshing. A local polygonal mesh strategy is performed employing polygonal finite element method to model the crack propagation. In order to model the singular crack tip fields, the convex and concave polygonal elements are modified based on the singular quarter point isoparametric concept that improves the accuracy of the stress intensity factors. Numerical simulations are performed to demonstrate the efficiency of various polygonal shape functions, including the Wachspress, metric, Laplace and mean value shape functions, in modeling the crack tip fields. Eventually, analogy of the results with the existing numerical and experimental data is carried out depicting accuracy of the propounded technique.

    ABSTRACT: In this paper, a tri-material adhesive system with nonlinear cohesive springs embedded between two elasto-plastic adhesive layers is proposed to predict the adhesive thickness effects on the fracture energy of bonded joints. The localized plastic and damage behaviours along the interface are described by the hardening cohesive zone models. The thickness dependent interfacial energy release rate is divided into the essential separation energy rate and the energy dissipation rate of the plasticization. The adhesive thickness dependent hardening cohesive zone model is implemented into the proposed numerical method to predict the failure of the adhesive joints. The validation of the model is performed by comparison with the experimental data.

    ABSTRACT: The blanking/trimming/cropping process introduces a substantial plastic deformation to the sheet metal and causes premature edge fracture during the subsequent forming process. In an attempt to understand how the blanking process affects edge fracture, an experimental and numerical study was undertaken on the plane-strain blanking process. Blanking tests on a DP780 steel sheet were carried out on a special fixture utilizing a in-situ microscope for the digital mage correlation (DIC) deformation measurement. The DIC method provides a detailed deformation field of the specimen that has not been reported in any other publications before. Interrupted tests were carried out to study the crack formation and propagation during the blanking procedure, while scanning electron microscope was applied to examine the blanked surface quality as well as the edge profile after test. Following the experimental study, a detailed finite element model with mesh size of 0.01 mm in the critical region was established for the numerical investigation. The model features (a) a non-associated Hill 48 flow rule, (b) von-Mises yield condition and (c) modified Mohr–Coulomb fracture model. With material parameters calibrated from the in-plane tests as well as accurate boundary conditions measured in actual tests, the finite element model accurately predicted the blanking process quantitatively. The current study also gave quantitative values of the parameters of interest during the blanking test, such as the global load displacement response and the local strain gradient history. The geometrical features of the blanked edge, i.e. the amount of roll over, the extent of the burnished zone and fracture zone were all accurately predicted by the present simulation.

    ABSTRACT: Conventional testing of fracture toughness measurement for thin metallic sheets is not possible owing to the large plastic zone ahead of the crack tip. Hence, the critical-crack tip opening angle (CTOAc) has been considered to be the key parameter to evaluate resistance of a thin sheet against stable crack propagation. In the present work, attempt has been made to measure the CTOAc of interstitial free high strength steel (IFHS) with 1 mm thickness using compact tension C(T) specimen. A high speed camera has been used for monitoring and imaging the progress of the crack length and crack tip angle during loading. The CTOAc measured from these photographs found to be 12∘±1.5∘. In these experiments, the crack tip velocity was also varied from 1.9 to 960 mm/min and no changes in the CTOAc value were observed. The high ductility of IFHS steel along with prevailing plane stress condition might be the reason of appreciably large CTOAc value.
