【Abstract】 From Maskhelishvili’s complex potential theory, the boundary integral method for the problem of finite plates is presented by using the pseudo orthogonal property of the eigenfunction expansion form in interface cracks. The formula of elastic T term for interface cracks problems is given. The elastic T terms for interface cracks problems of finite bimaterial plates with an edge crack along the interface, with subject to three kind of typical loading (uniform tension and compact tension and three point bend), are analyzed. The effects of material properties on T stresses are studied.更多还原
