Abstract. The plane strain problem of determining the dynamic stress intensity factors and strain energy release rates for moving collinear Griffth cracks at the interface of two dissimilar orthotropic half planes is considered. The problem is formulated in terms of a system of singular integral equations of the second kind which have finally been solved by using Jacobi polynomials. Graphical plots of the stress intensity factors and strain energy release rates for the problem of a pair of collinear interfacial Griffth cracks in di erent particular cases are presented.
