Abstract
A Boundary Element Method for the solution of three-dimensional prob-
lems of coupled quasi-static anisotropic thermoelasticity is developed. The
present formulation employs the fundamental solutions of the uncoupled
elliptic operators of anisotropic elastostatics and stationary heat transfer,
hence, the terms containing the dynamic effects and the coupling appear
under the domain integral in the representation formula. This domain inte-
gral is transformed to the boundary by the Dual Reciprocity Method. By
using decoupled fundamental and particular solutions, it is achieved that
the resulting damping and stiffness matrix possess the same structure as in
Finite Element analysis. For the time integration, a backward Euler scheme
is employed, and the results obtained with the
