FINITE ELEMENT STRESS ANALYSIS OF AXISYMMETRIC SOLIDS WITH ORTHOTROPIC, TEMPERATURE-DEPENDENT MATERIAL PROPERTIES.

Abstract

The finite element method is applied to the determination of displacements and stresses in axisymmetric solids with orthotropic, temperature-dependent properties. The continuous body is replaced by a system of ring elements with triangular or quadrilateral cross sections. Since elements are of arbitrary shape and can have different material properties, the procedure can be applied to bodies composed of many different materials of complex geometry. The analysis is used as a basis for the development of a general computer program which is capable of thermal stress analysis of axisymmetric solids. Mesh generating and temperature interpolating options allow the program to be readily used. A complete FORTRAN IV listing of the computer program is given in an appendix. (Author)
