Stress and Strain Analysis of Rotating FGM Thick Truncated Conical Pressure Vessel by Multilayer Modelling

The present research work aims to analyze displacement, stresses and strains, induced in functionally graded rotating thick truncated conical shells by finite element method. The shells are made up of functionally graded material, whose mechanical and physical properties vary in axial direction. Material properties are graded using Mori-Tanaka scheme. Shells are subjected to uniform internal pressure and have clamped-clamped boundary condition. For finite element modeling, linear quadrilateral element is used. Resulting displacement, stresses and strains due to centrifugal force and internal pressure are evaluated in ANSYS Mechanical APDL and the effect of grading parameter n on stress, strain and deformation is investigated.
