Abstract

Plates are widely used structures with one size being much smaller than two others. It is known that the loads on the plates are perpendicular to the plate surface. In today's structures, annular plates are designed according to the purpose of use such as storage tanks, machine industry and many engineering areas. In this study, numerical large deflection analyze of annular plates is studied. The solution of the problem is performed based on finite element method. The solutions obtained for different boundary conditions are compared with each other. Simply supported, fixed annular plates carrying uniformly distributed load were investigated by analytical and numerical methods. Stress, strain and displacement expressions are obtained for the annular plates numerically. The results of the numerical study are compatible with the analytical results based on theory of elasticity with large displacement theory of thin plates. It is observed that large deflection analyze of annular plates has a significant place to design engineering structures realistically.
