Abstract: This paper presents a boundary-domain element method (BDEM) for transient thermoelastic analysis in two-dimensional, isotropic, continuously non-homogeneous and linear elastic FGMs. Boundary-domain integral representations are derived from the reciprocity theorem by using fundamental solutions of transient coupled linear thermoelasticity for isotropic, homogeneous and linear elastic solids in the Laplace-transformed domain. A collocation method is employed in the numerical implementation. The Stehfest's algorithm is applied to obtain the time-dependent solutions. Numerical results are presented and discussed to verify the accuracy and efficiency of the presented BDEM.
