Web29 de mar. de 2024 · In this case, there are 4 slip systems with zero Schmid factor and 8 slip systems with the maximum Schmid factor as shown in Table 1. Dislocations on the 8 active slip systems can collide and react with one another, e.g., to form glissile junctions. A schematic representation of the glissile interaction mechanism is shown in Fig. 6a.

In materials science, critical resolved shear stress (CRSS) is the component of shear stress, resolved in the direction of slip, necessary to initiate slip in a grain. Resolved shear stress (RSS) is the shear component of an applied tensile or compressive stress resolved along a slip plane that is other than perpendicular or parallel to the stress axis. The RSS is related to the applied stress by a geo…
