Author Description

This series provides survey articles on the present state and future direction of research in branches of applied mechanics. Volume 30 supplies four articles covering: the mechanics of dislocations in strained-layer semiconductor materials, in which some specific issues with the mechanics of glide and interaction of dislocation in strained-layer systems are considered; propagating instabilities in structures, which provides a description of the phenomena with the help of results from experimental and analytical/numerical simulations; the plastic flow of crystals, which brings studies of multiple-slip interactions and hardening and of non-Schmid effects together within a time-independent theory, and explores their influence on strain localization; and elastic solids with many cracks and related problems, which focuses on physically important effects produced by crack interactions and presents results in the simplest form possible.
