2-DIMENSIONAL TIME-HARMONIC DYNAMIC COUPLED THERMOELASTICITY ANALYSISBY BOUNDARY-ELEMENT METHOD FORMULATION

A boundary element method is developed for time-harmonic analysis of a finite two-dimensional structure in dynamic coupled thermoelasticity. The advantage of the proposed technique is although it assumes a harm onic excitation, domain discretization is not required and a single re gion analysis can be done. The boundary integral equations of displace ment and temperature fields are considered and a single thermal excita tion is used to derive the boundary element equilibrium equations. Com parison is made and the coupling effect in natural frequencies, resona nce amplitudes and temperature distribution is investigated. (C) 1998 Elsevier Science Ltd. All rights reserved.
