Bizyuk A. The investigation of stress-strained state of an axisymmetric elastoplastic cylindrical shell under local impulse loading.

Axisymmetric elastoplastic cylindrical shells. The elaboration of method and software for calculations of shell stress-strain state parameter under local impulse loading. Method of elastic decisions in the version of the method of fictitious loading, numerical-analytical method of decomposition in rows, Laplace transformations, PC. The method of investigation of the process of high-rate elastoplastic shell deformation with taking into account complex loading parameter is elaborated. The results of influence of loading localisation, deformation speed on strength properties of construction, forming, destruction are given. It is created a new task decision method, which raising model adequacy and process analysis of high-rate elastoplastic anvelope deforming for account of complex calculation of wave process nature and physical properties of shell material. Given method can find its application attached to designing and SSS parameters analysis of constructions, which contain the shell construction element s under influence of momentary dynamic loading in energetics, machine-building, cosmic, aircraft industry
