The book considers and compares three dynamic mathematical models: elastic, quasi-static and elastic-plastic. The problems of impact and non-stationary interaction of absolutely hard bodies and fine elastic shells are solved. The results are presented in the form of figures and tables. It is shown that the elastic model of impact is convenient to use to calibrate the numerical process in solving impact problems and non-stationary interaction in elastic-plastic formulation.
This was achieved using a new methodology of solving dynamic contact problems in elastic-plastic dynamic mathematical formulation. Specifically, for elastic-plastic dynamic mathematical modelling, a new methodology of
destruction toughness KIc (T) determination has been developed. The book includes the results of calculations of destruction toughness for irradiated RPV reactor steel. There is a comparison of the results of the impact of solid
hard bodies and fine elastic shells and non-linear contact interaction developed using two approaches: 1) an elastic mathematical model and 2) an elastic-plastic mathematical model on the stage of elastic deformation.
