Abstract
Numerical methods for determining fracture mechanics parameters or “crack-driving forces” like J-integral or energy release rate and stress intensity factors by finite element analyses are presented and explained. Special emphasis is placed on the capabilities of the finite element code ABAQUS. Path dependence of the J-integral in incremental plasticity is addressed and rules for calculating physically meaningful J values are given. Likewise, experimental procedures for determining the fracture toughness in terms of J or K as codified in the ASTM standards are described, starting with a discussion on fracture mechanics terminology.
