Functionally graded segment of an epitrochoidal shells structures– The geometric nonlinear stress-strain analysis

The geometric nonlinear stress-strain state of functionally graded Epitrochoidal Shells under pressure and thermal environment is investigat-ed in this work. Material properties are taken as temperature dependent. Finite element solutions are obtained using the commercially soft-ware ANSYS. The effect of different geometry and material property parameters on the stress-strain state of functionally graded Epitro-choidal Shells under pressure and thermal environment is demonstrated. Finally, the change of the stresses, displacements, rotations and stains were investigated and presented. © BEIESP.
