An implicit solving algorithm adapted to numerical identification for simple lattice discrete element models of quasi-brittle materials
Résumé
A lattice discrete element model is presented to model quasi-brittle mate-rials behavior. The model is developed to enhance latter numerical identification and characterization of quasi-brittle materials under cyclic or multi-directional loadings. Em- phasis is put on the simplicity of the description of mechanisms furthering statistical and geometrical details instead of elaborate constitutive laws; and on the accuracy and the robustness of an original implicit solving procedure.
