Abstract
Abstract
The article presents the results of solving one of the fundamental problems in the field of increasing strength, service life, survivability, reliability and safety of welded joints in critical structures. A model for simulation of elasto-plastic welds failure in steel structures at cryogenic temperatures was developed. It proposed clarifying calculation and experimental methods for analysis and simulation of failure mechanisms taking into account types of forming defects. In addition, effect of heating and cooling cycles, kinetics of elasto-plastic deformation as well as fields of residual stresses and strains were used to predict the results.
