Dual boundary element method for three-dimensional thermoelastic crack problems

摘要

This paper describes the formulation andnumerical implementation of the three-dimensional dualboundary element method (DBEM) for the thermoelastic analysisof mixed-mode crack problems in linear elastic fracturemechanics. The DBEM incorporates two pairs of independentboundary integral equations; namely the temperature anddisplacement, and the flux and traction equations. In thistechnique, one pair is applied on one of the crack faces and theother pair on the opposite one. On non-crack boundaries, thetemperature and displacement equations are applied.
