Thermal-Static Structural Analysis of Isotropic Rectangular Plates Mervin Ealiyas Mathews1, Shabna M.S2 1Department of Civil Engineering, KMEA Engineering College, Ernakulam, India 2Department of Civil Engineering, KMEA Engineering College, Ernakulam, India ABSTRACT : Static and thermal analysis of isotropic rectangular plate made up of various materials with various types of load applications and different boundary conditions is analysed in this research. Both numerical and by finite element formulation are carried out in the analysis and the FEM formulation is done in the analysis section of the ANSYS package. In this study, flat rectangular plates without cut-out which can be assumed as prefect plate sand plates with a central rectangular …show more content…

With the Kirchhoff theory, the following assumptions are also considered: The transverse shears strain is equal to zero. However ϒxy does not equal to zero. After loading right angles in the plane of the plate may not remain right angles. The plate may twist in the plane. This implies that a normal remains normal. Єx = 0 means that change in plate thickness can be neglected and normal undergoes no extension. In-plane strains Єx and Єy in the stress-strain equations is negligible and normal stress σz has no effect on in-plain strains. The calculated stress can be higher than the yield stress of the material since no yielding is taken into account in the analysis. The plate is initially flat. Therefore, the in-plane deflections in x and y directions at the mid-surface are assumed to be zero. The material of the plate is elastic, homogeneous and isotropic. These assumptions result in the reduction of a three-dimensional plate problem into a two dimensional
