TI - Simulation of Dynamic 3D Crack Propagation within the Material Point Method T2 - Computer Modeling in Engineering \& Sciences PY - 2017 VL - 113 IS - 4 SN - 1526-1506 AB - This paper presents the principles and algorithms for simulation of dynamic crack propagation in elastic bodies by the material point method (MPM), from relatively simple two-dimensional cases to full three-dimensional, mixed-mode crack propagation. The paper is intended to give a summary of the latest achievements on simulation of three-dimensional dynamic crack propagation, which is essentially an unexplored area. Application of the methodology presented in this paper to several dynamic crack propagation problems has shown that the MPM is a reliable and powerful approach for simulating three-dimensional, mixed-mode crack propagation.
