Analyse numérique des contraintes résiduelles dans les bimatériaux céramique/métal

Finite element analysis of the thermomechanical behavior of metal matrix composites (MMC)

“…They show that, the propagation in modes I and II in the composites depends on the cracks location and the defects nature .Using the same method (FEM), Metehri and al [4] have shown that the level and distribution of residual stresses, in polymer matrices, are closely related to the fiber-matrix, fiber-fiber and fiber-interphase interaction. Boutabout and al [5] they analyzed numerically also, by the finite element method (FEM), the residual stresses developed in the copper-alumina and zirconia-alumina composite materials, they showed that these stresses are closely related to the gap between thermal expansion coefficients of these two constituents. Put the interface in shear.…”
