Abstract

The non-stationary boundary value problems of uncoupled thermoelastodynamics are solved. Two variants of the boundary integral equations are constructed, one of them in Laplace time-transformation space. For displacements definition the indirect potential method was used. The temperature field is determined on the base of direct method.. The computer reali- sation of BEM is demonstrated on examples of external boundary value problem for plane with arched holes by the action of impulsive heat flow. BIE in original space with use of re- tarding potential also are considered and there particulars are discussed. 1 Introduction The researches of boundary value problems in thermoelastic mediums with use of boundary element method (BEM) was first used for station
