✦ Synopsis

This paper deals with the growth characteristics of two interacting cracks in a mixed mode condition. The problem considered is that of two cracks of different lengths, arbitrarily placed in a plane. A uniform load is applied in the plane at a large distance away from the cracks. The objectives of this study are threefold: (1) Solve the mixed boundary value problem described in the foregoing; (2) Predict the most vulnerable crack tip where the instability would first occur as the load is increased; (3) Determine the directions in which the cracks may grow. The numerical results given are only for the specific case of one crack lying along a radial line which emanates from the tip of the other crack at an arbitrary angle.

When multiple cracks approach one another, the stress intensity factor changes due to the interaction of the stress field. This causes variation in the crack growth rate and shape of cracks. In particular, when cracks are parallel to the loading direction, their shape becomes non-planar due to the m
