Analyse Dynamique Des Plaques Orthotropes Par Simulation Numérique En Utilise Les Logiciel Ansys Etabaqus
Résumé: Orthotropic materials (composites) are of great interest in the field of modern industrial applications such as: mechanics, aeronautics, engineering civil and biomechanics given their hardness, lightness and super elasticity. During their operation and under the effect of external forces, these materials can undergo cracks or ruptures which can cause the disaster of the structure. In order to To avoid these types of problems, the dynamic analysis of these orthotropic materials is necessary in order to predict their dynamic characteristics and thus increase their lifespan. life. This analysis is essentially based on the internal structure of the material, its geometry, its boundary conditions, the frequencies and proper deformations. Our work consists of the dynamic analysis of two-dimensional thin orthotropic plates under the effect of homogeneous (EEEE) and non-homogeneous (AEAE) boundary conditions. using numerical simulation of modeling based on the finite element method under the ANSYS calculation code with thin isotropic plates and the ABAQUS
