Basic Principles of Constitutive Theories
The balance laws introduced in Chap. 2 are the fundamental equations common to all material bodies. However, these laws are insufficient to fully characterize the behavior of material bodies, because physical experiences have shown that two bodies of exactly the same size and shape, in general, will not have the same behavior when they are subjected to exactly the same environment (external supplies and boundary conditions). For example, the same force will not produce the same elongation on wires of rubber and aluminum of the same diameter and length.
