Abstract

Abstract

The Saint-Venant torsion problems of a composite cylinder with curvilinear crack were investigated.By means of considering the bimaterial interface as a boundary of outer bar or inner one,the problem was reduced to solving the boundary integral equations on crack,external boundary and interface.Using the new boundary element method,some typical torsion problems of a composite cylinder irnolving a straight or kinked crack were calculated.The obtained results were compared with the literature tada to prove the validity and applicability of the present method.
