Abstract:

The stress fields caused by the following cases are analytically computed 1 uniform slip in a cubical crystal at the interior of the aggregate 2 non-uniform slip in a cubical crystal in the interior 3 non-uniform slip in two closeby crystals in the interior, and 4 uniform slip in a crystal at the surface of the aggregate. In cases 1 and 4, the critical shear stress in the sliding crystal is uniform but the resolved shear stress is not. These 2 cases computed give stress fields caused by inclusions uniformly transformed in shape and give approximate stress fields for sliding workhardening crystals in an aggregate. In cases 2 and 3, the resolved shear stresses in the slipped region equal to its critical shear stresses and these 2 cases give the stress fields caused by sliding work-hardening crystals in the aggregate.
