Moving interfacial Griffith crack between bonded dissimilar media

[摘要] The plane strain problem of determining strain energy releaserate, crack energy, and crack-opening displacement (COD) for amoving Griffith crack at the interface of two dissimilarorthotropic half-planes is considered. The problem is reduced to apair of singular integral equations of second kind which havefinally been solved by using Jacobi polynomials. Graphical plotsof the strain energy release rate, crack energy, and crack-openingdisplacement for the problem in different particular cases are presented.
