High-rate elastic-plastic deformation of elements of modern technology is considered. Changes of properties of materials in a process of deformation under the action of impact and impulse loads are taken into account. Experimental studies to determine parameters of dynamic properties of material are reported. On the basis of three-dimensional models and numerical methods, an analysis of a stress-strain state of structural elements is carried out. The analysis of parameters of technological processes, proceeding at the expense of energy of explosion, is carried out. Calculation-experimental methods for analysis of deformation of cylindrical elements under impact loads are considered. The investigation results are used in practice.
