Statics is an area within the field of applied mechanics, which is concerned with the analysis of rigid bodies in equilibrium. In mechanics, the term equilibrium implies that the body of concern is either at rest or moving with a constant velocity. A rigid body is one that is assumed to ...

In this framework the virtual work equation is properly formulated by using a new simple approach that considers the new boundary of the body including the cracks surfaces. Then a condition on the loads, necessary and sufficient to the existence of the admissible equilibrium, is proven; this ...
