Abstract

The present work focuses on post-processing discrete modeling. Discrete models are used to describe failure of brittle and heterogeneous material. By noting that data obtained with these models are very close to those obtained with digital image correlation techniques (displacement fields), similar algorithms are applied to compute usual data such as strain fields. Different examples illustrate performances of the approach, in particular regarding the computation of stress intensity factors.
