Identification of heterogeneous elastoplastic behaviors using constitutive equation gap method

Résumé

To be able to identify cohesive zone models for heterogeneous materials, we need to estimate the local stress fields. The recent developments in imaging techniques allow now reaching local measurement fields (e.g. strain, temperature…). In this paper, an iterative procedure is used to identify the spatial material properties distribution and the local stress fields. The formulation and the principle of the method are presented, and its reliability is checked using finite element simulation data as reference full-field measurements. Finally, the method is applied on noisy measured displacement fields to assess its robustness.
