Numerical aspects of a problem with damage to simulate mechanical behavior of a quasi-brittle material

Abstract : This paper focuses on numerical problems related to the implementation of the non-local Mazars model in a Finite Element software Femcam developed in our laboratory. The model has been successfully applied for quasi-brittle materials. Several mechanical test cases are presented and validate the implementation. A sensitivity study concludes on the effect of the critical equivalent strain and internal length values on the global response of the material
