ВЛИЯНИЕ ОСТАТОЧНЫХ НАПРЯЖЕНИЙ В СВАРНЫХ СОЕДИНЕНИЯХ ТРУБОПРОВОДНЫХ СИСТЕМ НА ПРОЧНОСТЬ ПРИ ЭКСПЛУАТАЦИОННЫХ НАГРУЗКАХ
Keywords:Was analyzed influence of residual thermo stress in the durability of welded construction
AbstractIn the article on the bases of the finite element method and deformed solid body mechanics was discussed the problem of residual stress with coursed by thermo plastic deformation and stress concentration coursed by geometrical shape in a welding joint. Was defined stress-strain state under combined loading by residual stress and inner pressure in the pipe. Was analyzed influence of residual thermo stress in the durability of welded construction. It was taken as object of study the welding join according GOST 5264-80.
