TLDR
In this paper, a two-dimensional elastic-plastic computer program was adapted to calculate problems in plane stress as well as plane strain geometry, and a simulation of a tension test of a flat aluminum plate pulled to failure was calculated with the modified two dimensional program.Abstract:
In the study of ductile fracture it is useful to simulate fracture on the computer under plane stress conditions. In general, this is a three dimensional problem. Presented here is a method for adapting a two dimensional elastic-plastic computer program to calculate problems in plane stress as well as plane strain geometry. A simulation of a tension test of a flat aluminum plate pulled to failure is calculated with the modified two dimensional program. The results are compared with a fully three dimensional calculation. Finally a comparison is made with an experiment to demonstrate the effectiveness of the computational methods for studying fracture of work hardening materials.read more

Development of a formalism of movable cellular automaton method for numerical modeling of fracture of heterogeneous elastic-plastic materials
TL;DR: In this paper, a general approach to realization of models of elasticity, plasticity and fracture of heterogeneous materials within the framework of particle-based numerical methods is proposed, which is based on building many-body forces of particle interaction, which provide response of particle ensemble correctly conforming to the response (including elastic-plastic behavior and fracture) of simulated solids.

TL;DR: In this article, a formalism of the movable cellular automata method for simulation of consolidated heterogeneous elastoplastic media at different scale levels is presented. But the authors do not consider the effect of structural scale levels higher than the level under consideration by combining the particle method and conventional methods of continuum mechanics.
