Non-linear models consider that the structure is pre-stressed and is plastically deformed. Linear models consider simple parameters and assume that the material is not plastically deformed. Structural analysis consists of linear and non-linear models. In case of structural failure, FEA may be used to determine the design modifications to meet the required conditions. Because of its characteristics, researchers are able to verify a proposed design to the user’s specifications before manufacturing or construction. FEA is used in new product design, and existing product refinement. Because of its flexibility in ability to discretize the irregular domains with finite elements, this method has been used as a practical analysis tool for solving problems in various engineering disciplines. Nodes are usually located along the element boundaries, and they connect adjacent elements. Included in terms of field variables at specific points referred to as nodes. These functions (also called interpolation functions) are, For each element, systematic approximate solution is constructed by applying the variational or weighted residual methods. To overcome this difficulty FEA is used the system is discretized into a finite number of parts known as elements by expressing the unknown field variable in terms of the assumed approximating functions within each element. While the analysis is being carried out, the field variables are varied from point to point, thus, possessing an infinite number of solutions in the domain. INTRODUCTION Finite element analysis (FEA) is a powerful computational technique used for solving engineering problems having complex geometries that are subjected to general boundary conditions. Key words: Finite element analysis (FEA), isotropic rectangular plate, ANSYS, static analysis. During this analysis, the optimal thickness of the plate has been obtained when the plate is subjected to different loading and boundary conditions. Numerical results showed that, the results obtained by finite element analysis and ANSYS simulation results are in close agreement with the results obtained from exact solutions from classical method. Finally, comparison has been done between the results obtained from FEA numerical analysis, and ANSYS results with classical method - exact solutions. This job is helpful for obtaining the results not only at node points but also the entire surface of the rectangular plate.

Later, for the same structure, analysis has been carried out using finite element analysis software ANSYS. Numerical analysis (finite element analysis, FEA) has been carried out by developing programming in mathematical software MATLAB and the results obtained from MATLAB are giving good agreement with the results obtained by classical method - exact solutions. In this paper, finite element analysis has been carried out for an isotropic rectangular plate by considering the master element as a four noded quadrilateral element. This research work aims to analyze the static analysis of an isotropic rectangular plate with various boundary conditions and various types of load applications. 2 Department of Mechanical Engineering, National Institute of Technology -Rourkela, Odissa-769008, India.
