WebThe crystal structure is the arrangement of atoms in a crystal. It is represented by a lattice of points which repeats a basic pattern, called a unit cell, in three dimensions. The lattice can be characterized by its … WebWhen a rock or mineral is subjected to stress, stress is proportional to strain as long as the elastic limit has not been exceeded. This relationship is known as Hooke's law. Plastic deformation takes place when a rock, mineral, or other substance is stressed beyond its elastic limit ( Fig. 1 ). Plastic deformation is that deformation that ...
