ABSTRACT
In this chapter, we will look at crystal plasticity, which is based on the observation that there are preferred planes and directions on which dislocations will move in a single crystal. The motion of dislocations and the process of twining normally are identified as the primary sources of plastic flow in single crystals. Even though we will not focus on dislocations and their specific motion, the theory of crystal plasticity we develop in this chapter is directly motivated by these motions in a single crystal.
