Chapter 2 Deformation and Strain
In this chapter we explain how deformation is described precisely. This gives us the framework to model the deformation of a metal beam for example, which is holding up a building (although we wont do this problem here).

In this chapter we explore the governing eld equations: the conservation of mass and linear momentum, the balance of angular momentum, and the conservation of energy. Although we refer to these principles as laws, they are postulate

In the 1950s and 1960s, thermodynamics was combined with classical continuum mechanics to form a rational method for developing constitutive equations. These methods were pioneered by A. C. Ering
