Article
The existing smoothed particle hydrodynamics (SPH) approaches for propagating fatigue cracks involve either the deletion of the crack front particle or stopping all its interactions in the total Lagrangian form. Here, we adopt the pseudo-spring-based Eulerian form of SPH to model mode-I fatigue crack propagation. For modelling fatigue crack growth,...

Smoothed particle hydrodynamics (SPH) based on Eulerian kernels is widely-used in large deformation analysis of geomaterials. Despite being popular, it has tensile instability and rank-deficiency; thus, it needs several numerical treatments to be stable. In this work, a stabilized total Lagrangian SPH method is presented, which is inherently free o...
Article
Significant advances in nanoscale research have enabled the continuous miniaturization of devices. With the reduction in the size of the devices, it is important to identify if the continuum scale methods remain applicable to such small-scale systems. Motivated by this, the present work tries to understand the equivalence, or its lack thereof, of t...
Article
This paper presents numerical simulations of metal machining processes with Eulerian and Total Lagrangian Smoothed Particle Hydrodynamics (SPH). Being a mesh-free method, SPH can conveniently handle large deformation and material separation. However, the Eulerian SPH (ESPH) in which the kernel functions are computed based on the current particle po...
Article
The ceramic and ceramic-metal composite plates upon high velocity impact by a kinetic energy rod may undergo spalling, fragmentation, interface debonding, perforation, bending, and stretching. A challenge in studying these problems is using a material model that realistically simulates the material response at high plastic strains, plastic strain r...
Article
The behaviour of circular plates made of Weldox 460E steel under projectile impact are numerically investigated by the pseudo-spring Smoothed Particle Hydrodynamics (SPH) framework. The Johnson-Cook material model is used to consider the plastic deformation of materials. Six damage models (Wilkins, maximum shear stress, constant fracture strain, Co...
Article
In this paper crack initiation, propagation and branching phenomena are simulated using the Pseudo-Spring Smoothed Particle Hydrodynamics (SPH) in two and three-dimensional domains. The pseudo-spring analogy is used to model material damage. Here, the interaction of particles is limited to its initial immediate neighbours. The particles are connect...
Article
Mesh-free particle methods applied to continuum fluid dynamics still use fictitious, ghost or virtual particles, and/or molecular dynamics concepts in the treatment of the boundaries. The aim of this paper is to present the implementation of the physical reflective boundary conditions (RBC), based on Newton’s restitution law and the foundations of...
Preprint
Conventional smoothed particle hydrodynamics based on Eulerian kernels (CESPH) is widely-used in large deformation analysis in geomaterials. Despite being popular, it suffers from tensile instability and rank-deficiency; thus, it needs several numerical treatments to be stable. In this work, we present a stabilized total-Lagrangian SPH method (TLSP...

An algorithm is proposed to model crack initiation and propagation within the Total Lagrangian Smoothed Particle Hydrodynamics (TLSPH)framework. TLSPH avoids the tensile instability encountered in conventional Eulerian kernel-based Smoothed Particle Hydrodynamics (SPH)by making use of the Lagrangian kernel. In the present approach, the support doma...

Conference Paper
The virtual optimisation of tooling equipment is nowadays one of the common challenges in mechanical serial production. Even some numerical Eulerian approaches (grid-based) exist for modelling solid materials under dynamic loading, most of them are not very successful. Especially the solids undergoing large deformation and the subsequent material s...
Article
Energy conservation and consistency are not easy to achieve simultaneously in SPH. In this study an efficient strategy is proposed to achieve energy conservation in a SPH framework with consistent basis function. Herein, at every particle pair interaction a correction term is introduced such that the energy conservation is restored locally and at t...
Article
Dynamics of a Newtonian fluid in a cylindrical symmetric domain can be conceptualized as axisymmetric flow. Full-scale 3D simulation of such problems requires large computational overhead. A new divergence-free Axisymmetric Incompressible Smoothed Particle Hydrodynamics (AxISPH) framework is proposed for modeling of Newtonian fluid flow with free-s...
Article
In addition to an accurate mathematical representation of the material, a computational modelling method for assessing impact problems involving large plastic deformation, damage localization, fracture etc. requires a suitable discretization scheme which can simulate the relevant physical processes without introducing any numerical artifact or bein...
Article
When ceramic or ceramic-metal composite structures are subjected to impact loading, they undergo various deformation phases such as plastic yielding, pulverization, fragmentation, tensile spalling, interface debonding, penetration etc. In order to study these phenomenological characteristics and produce insightful observation, numerical simulation...
