ENDOMMAGEMENT, RUPTURE ET CHANGEMENTS D'ÉCHELLES DANS LES MATÉRIAUX HÉTÉROGÈNES

Abstract : The analyses presented in this dissertation deal with damage and failure of heterogeneous materials. The main degradation mechanism is cracking at the lowest level. A probabilistic approach constitutes a useful tool. Brittle materials (such as ceramics, SG cast iron under cyclic loadings) or quasi-brittle materials (e.g., impacted ceramics, fiber-reinforced ceramics, cementitious matrices reinforced by short or continuous fibers) are concerned. The dialogue between different scales is used to build models predicting darnage and failure. On the other hand, different identification strategies are developed to identify the material parameters.
