Essay

There is developed an application of the variation-difference method for solving problems of the theory of small elastic-plastic deformations with respect to the elements of constructions with the stress concentrators taking into account the linear strengthening of the material and unloading. The zones of evolution of plastic deformations for step enlarging of the loading are constructed, the influence of strengthening onto the development of these zones is established, and the remaining deformations and the limit loads are obtained. On the base of solving contact problems of the theory of small elastic-plastic deformations, there is revealed an advantage of forming of connection of armature bars by a pre-heated socket.
