Abstract
A 2D Peierls model is developed to determine the critical
shear stress to transmit a screw dislocation across a
coherent interface. An idealized geometry is considered
in which the incoming and outgoing slip planes are
coplanar and perpendicular to a coherent interface. The
incoming and outgoing slip planes and interface are
described by a local shear stress-shear displacement
relation that reflects the gamma surface for that region.
Several approaches to increase the critical resolved shear
stress for transmission are highlighted. A particularly
potent strategy is to decrease the strength of bonding
across the interface, so that the dislocation is trapped via
