Abstract
On the basis of the small elastic-plastic deformations theory boundary tasks for three-dimensional rods under variable elastic-plastic loadings, taking into account secondary plastic deformations, are formulated. Approximation for boundary tasks based on A.A. Samarsky and I.V. Fryazinov modification is carried out. The stress-strain state of the rods taking into account elastic unloading and secondary plastic deformations is researched. A comparative analysis of the residual calculated values is carried out.
