Finite element solution for axisymmetric transient thermal stresses

Abstract

A finite element formulation for solving axisymmetric transient heat conduction and thermal stress problems is developed in this thesis. The governing equations of uncoupled, linear, isotropic thermoelasticity are discretized using quadratic isoparametric elements. A FORTAN IV program, using double precision arithmetic, is presented. Compact storage techniques for banded symmetric matrices are used. Comparison between exact and computer solutions demonstrate close agreement for a number of test problems. Detailed instructions for using the program are included.
