Abstract

The purpose of this paper is to discuss a new approach to non-local interactions during failure in quasi-brittlematerials. It focuses on the estimationof thenon-local weightfunctionsdirectly from interactions. The materials is modeled as an assembly of inclusions and the elastic interactions upon dilation of each inclusion are computed in a similar way to a classical Eshelby’s problem. A new interaction-based weight function is then built from these interactions. This new interaction- based non local model is validated on simple 1D problems and its performances are compared with the classical integral-type nonlocal model.
