Study of the Effect of Crack Location in Bi-Material Plates
Keywords:
Cracks, Interface, bi-material, X-FEM, locationsAbstract
The Bi-Material structures are characterized by the fact that they possess a specific behavior. This feature often requires complex formulations to achieve realistic mechanical behavior. In addition, if there is a crack in the interface and if it reaches a critical condition, the crack may extend along the interface, provided that the interface is sufficiently weak compared to one or the other material. The mechanical modeling of interfacial cracks is carried out by the extended finite element method (X-FEM). The objective of this paper is to study the location of crack in bi-material plates. We took several locations of cracks. The results obtained are satisfactory.
