Abstract
This work investigates the dynamic stress intensity factor for a crack in an infinite elastic medium. Two classes of special problems of thermoelasticity are considered. These are the problems of classical elastodynamics and quasi-static problems of uncoupled thermoelasticity. The boundary value problems in these fields are recasted in an integral form. The boundary integro-differential equations are solved by the boundary element method in the Laplace transformed domain. The method is illustrated by two numerical examples for harmonic and impact load in elastodynamics and harmonically varying temperature load in thermoelasticity.
