Development and Validation of a Finite Element Based Method to Determine Thermally Induced Stresses in Bonded Joints of Dissimilar Materials.

Abstract

A validation is carried out of the steady state thermal stress analysis capability of the PAFEC Finite Element program. Two problems are considered for which closed form solutions can be obtained: these comprise the thermal stresses in a heated circular plate and also a bonded joint. Also, a procedure is developed for calculation of residual stresses in bonded joints. Comparisons with closed form solutions indicate the degree of discretisation necessary to achieve accurate results.
