Waves in Rods, Vibrations of RodsStatic forces and static deformations have been considered in the previous chapter. If, however, an elastic body is under the action of a force varying in time, different types of waves can arise in this body. Each type of wave can transfer disturbances from one part of the body to the other at a finite speed.

General Theory of Stress and StrainLet us now proceed to the general theory of the behaviour of an elastic body under the action of external forces. Our discussion in this chapter is not restricted to isotropic bodies, i.e., bodies whose characteristics are the same in all directions, but is also applicable to crystals of arbitrary symmetry.
