This analysis extends the results of a previous paper by H. C. Lee (1) in which a generalized minimum principle is applied to a wedge. Similar results are obtained by the use of integral equations. Two types of integral equations are shown, one in a pair of equations and the other in a single equati

This paper is concerned with the plane strain problem of a crack that terminates perpendicularly at the interface of a bonded composite. An integral JR,, is proposed. By the asymptotic analysis, it is shown that, so laong as R o is within the K-dominant region, JR0 = KZ,R6Z"+'((1 -u2)/2pL2)H. Here,
An application of the time-domain boundary integral equation method (TBIEM) to the case of rapidly moving cracks in a continuum is presented. The major objective of this paper is to explore the potential of the TBIEM in solving problems in dynamic fracture where inertia effects cannot be ignored. In
The J-integral is derived for mode I and mode II cracks in orthotropic composite materials and it is shown to be independent of the integral path around the crack tip. The J-integral is then extended and applied to a newly developed energy based fracture criterion for orthotropic composite materials
