Theoretical and experimental modeling of deformation of a cylindrical shell made of 45 steel under complex loading

Thin-walled cylindrical shells are used in elements of highly loaded products mechanical engineering and energy. Along with their frequent use production, experimental research laboratories is also carried out constantly. This allows to simulate the behavior shell when exposed external forces. But sometimes conducting an experiment becomes little possible due limitation power apparatus modeling corresponding conditions exposure practice, therefore, improving theoretical methods for calculating limiting states working elastoplastic region relevant. The purpose study verify conformity results conducted on a thin-walled made steel 45 (GOST 1050-2013) sample by stretching, compression torsion forces calculations based equations theory elastic-plastic processes A.A.
