It is with pleasure and gratitude that this work is presented on the commemoration of the 60th birthday of Prof. A simple model is constructed which adequately captures the dependence on stacking fault energy and elastic modulus mismatch. A significant new result is that the critical resolved shear stress increases with the unstable stacking fault energy of the slip planes, but is relatively insensitive to the maximum shear strength of the slip planes. Numerical results in this regime confirm the Pacheco and Mura observation that the critical resolved shear stress is proportional to the mismatch in elastic shear modulus. The geometry is specialized to the case when slip planes are perpendicular to the interface and numerical results are obtained for values of mismatch, Δμ, in elastic modulus equal to 20% of the average value. This study extends the work of Pacheco and Mura (1969), by using a numerical approach that incorporates a variety of slip plane relations and by adopting a formulation by Beltz and Rice (1991) that accounts for the finite interplanar spacing across a slip plane.
