8-Node Quadrilateral Matlab Code for Finite Element Analysis

Abstract

The purpose to this work to provide mathematical approach to developed MATLAB code for 8-node quadrilateral element for finite element analysis of 2-D structure to improve accuracy in results. In present investigation 8-node quadrilateral element MATLAB code is proposed for structural analysis of 2-D Isotropic elastic structures. The meshing of cantilever beam is done with 8-node elements which are subjected to static loading condition. In this paper MATLAB code is implemented on cantilever beam and the result obtained is also validated with ANSYS software. Moreover, this code can also be modified for Messerschmitt-Bolkow-Beam and complete MATLAB code is also presented in appendix. The developed MATLAB code can universally adopted for other analysis such as topological optimization, thermal analysis, dynamic loading condition etc.
