Abstract

FEM has become an indispensable tool for the stress analysis of crack configurations in elastic-plastic materials, as the physically and sometimes geometrically non-linear IBVPs in finite structures are not solvable with analytical methods. To model the material behavior, predominantly the incremental laws of plasticity with various hardening types introduced in Sect. A.4.2 come in to question. Here too, the goal of the computations is to determine the fracture-mechanical loading parameters for ductile crack initiation and crack propagation.
