Abstract

Boundary element analysis of 3-D problems in coupled thermoelasticity M. Tanaka, T. Matsumoto, M. Moradi Department of Mechanical Systems Engineering, Faculty of Engineering, Shinshu University, Nagano 380, Japan This paper deals with a new boundary element method for analysis of the quasi-static problems in coupled thermoelasticity. Through some mathematical manipulation of the Navier equation in elasticity, the heat conduction equation is transformed into a simpler form, similar to the uncoupled-type equation with the modified thermal conductivity which shows the coupling effects. This procedure enables us to treat the coupled thermoelastic problems as an uncoupled one. A few examples are computed by the proposed BEM, and the results obtained are compared with the analytical ones available in the literature, whereby the accuracy and versatility of the proposed method are demonstrated. Introduction Computational mechanics has been so well developed that the computer analysis softwar
