Semi-infinite moving crack under antiplane shear loading

The article deals with the study of a moving interfacial semi-infinite crack situated between two orthotropic strips of different composite materials. The crack surface is under the shear wave disturbance. The governing equations have been solved by applying the Fourier transform technique to get the desired standard form of the Wiener–Hopf equation, which is further solved by using the Wiener–Hopf method. The analytical asymptotic expressions for physical quantities like stress intensity factor (SIF) and crack opening displacement (COD) for the crack have been obtained. The nature of SIF and COD for different combinations of composite materials and also for various depths of the semi-infinite strips has been depicted graphically.
