The minimum principle and the maximum principle, complementary to each other are established in order to evaluate the energy-release corresponding to prescribed crack shape in the elastic body. Frictionless bounds of the crack surfaces are considered. A new approach to the problem proposed in the study is based on methods of convex analysis. A brief introduction to the concepts of convex analysis used in the study is presented in the appendix.
