✦ Synopsis

It is shown that standard forces alone are unable to account for the bodyÕs response to the evolution of material structures with time. It is also shown what configurational forces, both at a distance and at contact, are needed to give a complete picture of the bodyÕs response. Moreover, representations of these configurational forces are given in terms of standard constructs, such as the first and second deformation gradients, the Piola stress, and the free-energy density.
