Abstract In recent years, the study of the behaviour of damaged structures has been focusing on cracked components in presence of an extensive material yielding at the crack tip; under this condition, linear elastic fracture mechanics theory is not able to describe the real stress-strain state at the crack tip and consequently either the static or the fatigue behaviour of the component. In this work, an extensive parametric numerical analysis of the plastic zone size and shape at the crack tip for a through cracked plate under Mode I loading condition is presented. The obtained results More >
