Abstract

Abstract This chapter analyzes the response of solids to stress. The defining property of a solid is its ability to resist shape changes in the presence of external stresses. Stress, defined as force per unit area, can be divided into two classes: compression and shear. The remainder of the chapter derives expressions for the following: stress tensor, strain tensor, Hooke’s law, energy density, elastic module of cubic and hexagonal systems, distortions of a cubic crystal, elastic waves, elastic waves in a cubic crystal, isotropic media, viscosity in solids, and the measurement of elastic constants of materials. Sample problems are also provided at the end of the chapter.
