Three-Dimensional Finite-Element Computer Program - User's Guide

Abstract

The FORTRAN Listing and User's Guide for a Three-Dimensional Linear Thermal-Elastic Finite-Element Computer Program is presented. The program will determine three-dimensional displacement and stress distributions for laminated orthotropic composite materials. A curved isoparametric element with 24 nodal points and 72 degrees-of-freedom is used to model the individual layers of a laminate. The nodal displacements are determined by minimizing the total potential energy of the system, at the element level, with a conjugate gradient iterative method. The program is presently (1974) running on an IBM 370/158 computer at Virginia Polytechnic Institute and State University.
