Abstract:

The aim of study is static bending analysis of an isotropic circular plate using analytical method i.e. Classical Plate Theory and Finite Element software ANSYS. Circular plate analysis is done in cylindrical coordinate system by using Classical Plate Theory. The axisymmetric bending of circular plate is considered in the present study. The diameter of circular plate, material properties like modulus of elasticity (E), poissons ratio (µ) and intensity of loading is assumed at the initial stage of research work. Both simply supported and clamped boundary conditions subjected to uniformly distributed load and center concentrated / point load have been considered in the present study. In this research work, the effect of varying thickness of the plate on its deflection and bending stress is studied. So, the key point of research work is thickness variation of plate. Modeling and analysis of circular plate is done in ANSYS APDL.4noded shell 181 element is used for modeling of circular plate. Once deflection is obtained by using CPT, bending moments and bending stresses are easily calculated by usual relations. Analytical results of CPT are validated with ANSYS results.
