Abstract:

The FORTRAN Listing and Users 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 370158 computer at Virginia Polytechnic Institute and State University.
