Abstract
Damage in a solid results from microscopic movements. We decide to inc lude the power of these movements in the principle of virtual power. B ecause the microscopic velocities are related to the damage rate, the power of the internal forces we choose depends on the damage velocity and also on its gradient to take into account interactions. The models resulting from this theory are coherent and describe the main experim ental properties, for instance the unilateral phenomenon. Concrete is chosen as an example to illustrate the theory.
