Finite Element Analysis of a 2-D Linear Static Structure (Flat Plate) Using Matlab

Abstract

A finite Element method approach has been developed for structural analysis of various industrial products. It helps to analyze and solve the problem of structural displacement due to various internal and external forces. And it also helps in the calculation stresses and strains. This method can be applied to typical MEMS structures such as beam, plate and other complex structures. The theoretical analysis of the finite element method is well established in the case of the triangular or tetrahedral meshes. In this case we use 4-node rectangular mesh, for the analysis of a flat plate of uniform thickness with the help of Matlab. Our theory supported by the some numerical experiments, which are taken from various engineering application, ranging from elasticity and in other forces and stress analysis.
