摘要：
The reliability and efficiency of the semi-analytic finite element method in the problems of geometrically nonlinear elastic-plastic deformation of axisymmetric structures under the influence of dynamic loads are considered. The possibilities of the technique are demonstrated on the examples of numerical simulation of the building structures' stress-strain state with large linear deformations and technological operation analysis of impulse metal processing.
