• Article: On the deformation and failure of Al 6061-T6 at low triaxiality evaluated through in situ microscopy
[Hide abstract]
ABSTRACT: We investigate deformation and failure of Al 6061-T6 at low triaxiality conditions through in situ scanning electron microscopy. The global behavior of the specimen, as well as the local deformations of the matrix material, second phase particles, and preexisting voids, are observed with a combination of high temporal/low spatial resolution images and low temporal/high spatial resolution images. It is found that the matrix dominates the deformation response, with the second phase particles and voids imparting little influence on the deformation. Tracking of second phase particles is used to determine the local strain fields averaged over a suitable gage length and to correlate to the macroscopic behavior.

• Article: An analysis of the influence of grain boundary strength on microstructure dependent fracture in polycrystalline tungsten
[Hide abstract]
ABSTRACT: This work examines the influence of changes in grain boundary (GB) strength on microstructure dependent crack propagation in polycrystalline tungsten (W). The property of focus is brittleness index (BI) originally introduced by Evans and Marshall in 1976 and 1979, respectively, used in order to quantify the extent of brittleness of a material. In an earlier work, GBs of Ni-doped polycrystalline W have been characterized for embrittlement using ab-initio quantum mechanical simulations as a function of Ni atomic volume fraction and GB thickness. This work focuses on quantifying the influence of GB strength on microstructure dependent crack propagation. Continuum mechanical GB strength properties and effective W grain properties are derived from ab-initio simulation based stress–strain curves. The crack propagation simulations when GBs are considered of finite width are based on an extended finite element (XFEM) framework. Simulations that consider GBs of infinitesimal width due to mesh resolution issues are based on a combined XFEM-cohesive finite element model that employs cohesive elements at GBs. Analyses of crack propagation through finite width GBs focus on understanding the role of square root of length scale dimension in the original BI formulation. Based on analyses of crack propagation through finite width GBs oriented at angles varying from $$0^{\circ }\,\hbox {to}\,90^{\circ }$$ with respect to advancing crack, a quantitative criterion based on a failure index which predicts crack propagation path in polycrystalline W is proposed and examined.

• Article: An improved numerical manifold method incorporating hybrid crack element for crack propagation simulation
[Hide abstract]
ABSTRACT: The numerical manifold method (NMM) simulates continuous and discontinuous problems in a unified framework; thus NMM has advantages in analysing crack propagation. However, calculation of the stress intensity factors (SIFs) when adopting the NMM requires additional procedures, such as the J-integral and the interaction integral. In this study, a hybrid crack element (HCE) method is incorporated into the NMM to directly obtain the SIFs; the new algorithm combines the merits of both the NMM and HCE method. In the proposed algorithm, the HCE is used in the crack-tip region while the NMM is applied in the remaining region. The SIFs at the crack-tip are calculated directly from the solution of the governing equation with less computational complexity relative to existing methods. The proposed algorithm does not require any changes to the initial mesh during crack propagation. It is verified by a few examples and the results show that the simulated crack propagation paths are in good agreement with the results from existing studies while the computational efficiency is improved due to the direct calculation of the SIFs and the consistency of the mesh system in the crack propagation process.

• Article: A criterion for ductile fracture based on continuum modeling of energy release rates
[Hide abstract]
ABSTRACT: A continuum model of ductile fracture initiation is presented which is based on consideration of the work done on the system sufficient to cause release of the binding energy necessary for crack formation. The fracture criterion is posed for plastic materials with no pre-existing crack as a critical state reached when the energy release rate of the bulk system is balanced by the energy release rate associated with the fractured medium. Two fracture modes are considered which are commonly addressed in fracture mechanics: mode I crack opening perpendicular to the fracture plane and mode II shear rupture tangential to the fracture plane. A study of the use of the criterion for a plastic material with power law hardening is examined and compared with published experimental data and empirical criteria.

• Article: Biaxial experiments and phenomenological modeling of stress-state-dependent ductile damage and fracture
[Hide abstract]
ABSTRACT: The paper discusses an anisotropic continuum damage and fracture model for ductile metals. The phenomenological approach takes into account the effect of stress state on damage and failure criteria. Different branches of the criteria are considered corresponding to various microscopic mechanisms depending on stress intensity, stress triaxiality and the Lode parameter. To validate the proposed framework different experiments with biaxially loaded specimens and corresponding numerical simulations have been performed. Digital image correlation technique has been used to analyze current strain states in critical regions of the specimens.

• Article: A three dimensional augmented finite element for modeling arbitrary cracking in solids
[Hide abstract]
ABSTRACT: This paper presents a new three dimensional (3D) augmented finite element method (A-FEM) that can account for arbitrary crack initiation and propagation in 3D solids without the need of additional DoF or phantom nodes. The method permits the derivation of explicit, fully condensed elemental equilibrium equations which are of mathematical exactness in the piece-wise linear sense. The method has been implemented with a 4-node tetrahedron element and a simple local tracking algorithm has been employed for calculating and recording the evolving planar or non-planar crack surface. It has been demonstrated through ample numerical examples that the new 3D A-FEM can provide significantly improved numerical accuracy and efficiency when dealing with crack propagation problems in 3D solids with planar or non-planar crack surfaces.

• Article: An adhesive zone model for polymeric interfaces
[Hide abstract]
ABSTRACT: In this work we develop an adhesive zone model for polymeric interfaces, which describes the kinetics of dissociation and association of polymer chains bridging the interface. Compared with previous works on interfacial bond rupture, our adhesive zone model includes two novel features: possibility of bond reforming and a highly nonlinear force–extension relationship for the polymer chain motivated by previous experimental measurements. The absence of these two features was demonstrated in an earlier work to cause unphysical crack propagation under zero load as well as overextension of the chains beyond their full contour length. Using the rate dependent crack propagation in a double cantilever beam, which may be elastic or viscoelastic, as an example, the new adhesive zone model is shown to correct the unphysical results obtained earlier. Specifically, it leads to a significantly increased adhesive fracture energy, i.e., the energy per unit area required to rupture the chains on the interface, for slow crack propagation, owing to the ability to achieve a dynamic equilibrium of bond dissociation and association. Furthermore, the nonlinear chain model predicts a near-catastrophic decrease in chain density as the finite extensibility limit is approached. This results in an adhesive fracture energy which is orders of magnitude smaller than that predicted by the linear chain model for fast crack propagation. Although the adhesive zone model has only been applied to a double cantilever beam in this work, it is a generic model for polymeric interface, and can be implemented in finite element models to simulate fracture in bulk polymers in general.

• Article: General remarks on cyclic cohesive zone models
[Hide abstract]
ABSTRACT: Cyclic cohesive zone models represent powerful numerical tools to describe and predict different phenomena of fatigue. In the present paper a review is given about the state of the art of cyclic cohesive zone modelling. Firstly, a commented survey of the history of cyclic cohesive zone models is presented starting from the strip-yield models of Dugdale and Barenblatt and ending with the modern creep-fatigue models. Next, the paper focuses on the thermodynamically consistent formulation of cyclic cohesive zone models. In particular, the formulation of cohesive zone potentials, the choice of appropriate deformation and damage measures as well as the assembly of damage evolution equations are discussed in detail. In this context, established models are critically compared with a model recently proposed by the authors. Finally, some numerical examples are presented for illustration, dealing with fatigue crack growth, uniaxial fatigue life prediction, and intergranular fatigue damage. These simulations demonstrate the wide range of applications of cyclic cohesive zone models.

• Article: Evaluation of transformation region around crack tip in shape memory alloys
[Hide abstract]
ABSTRACT: When an edge cracked shape memory alloy (SMA) plate is loaded, phase transformation around the crack tip results in a non-homogeneous region composed of austenite and martensite phases that affects its fracture behavior. In this work, the size of the phase transformation region surrounding the tip of an edge crack in a thin SMA plate is calculated analytically using a transformation function that governs forward phase transformation, together with crack tip asymptotic stress equations. Stress intensity factors required in the asymptotic equations are obtained from a least squares fit of full displacement field, calculated using finite elements, to asymptotic near-tip opening displacement equation. The present work predicts the size and shape of the transformation region in closed form. For comparison purposes, the region is also calculated using ABAQUS with user defined material subroutines (UMAT) for plane strain and plane stress. Transformation regions calculated analytically and computationally are plotted with experimental, analytical and numerical results available in the literature; the results show a good agreement with the experimental results.
