“…That added a rationalization of the calculations and a huge benefit of modeling distinctive types of cracks with different orientations. The method gave great precision on the paperwork of Bouziane et al [36], where a numerical example of a center cracked plan with uniaxial tension was investigated in two cases of homogenous materials and bi-materials. Also the study of Mohamed Ben Ali et al [37] on sandwich structures with two cases of symmetrical double cantilever beam and asymmetrical double cantilever beam.…”

The material with anisotropic properties are becoming widely essential due to the ease to manipulate their mechanical properties in order to obtain a particular quality, insure safety or a specific behavior. Those kind of materials are considered anisotropic because their characteristics and behavior are dependent to every direction of the material’s orientation. In this work, the virtual crack closure-integral technique is implemented to a mixed finite element, in addition with the stiffness derivative procedure, to evaluate the energy release rate of crack extension in anisotropic materials. A simulation of a cracked edge rectangular plat with anisotropic characteristics is taken for example. The results obtained are in good agreement with the analytical results, making the proposed technique a good model for fracture investigation and allow it to study more complicated cases in future works.
