Analysis of Deflection of Rectangular Plates Under Different Loading Conditions

Abstract

In this paper, bending of an isotropic rectangular plate under various loading conditions is studied using MATLAB code and commercial finite
element software ANSYS. Classical plate theory (CPT) and plane stress assumption are used. Also, four node rectangular nonconforming elements
are used. The presented code is able to consider residual stresses, self-strains, body forces, distributed and concentrated forces and distributed
moments. Furthermore, it can analyze different boundary conditions for the plate. The results of finite element analysis are compared with each
other and also by CPT results and a good agreement between them is noticed. On the other hand, the convergence of results is investigated by
increasing the number of elements.
