Paper Title:
Influence of Material Parameters on Plasticity Induced Crack Closure
  Abstract

Plasticity Induced Crack Closure (PICC) is an important fatigue phenomenon affecting crack growth under cyclic loading, which makes important to consider it in the design of components. In this paper a parametric study that correlates elastic-plastic material parameters with plasticity induced crack closure (PICC) is presented. Yield stress and hardening coefficient were selected as the material parameters of interest and a sensitivity analysis was developed. The influence of the different parameters on PICC is explained based on the analysis of crack tip micromechanisms for plastic deformation.
