Abstract
Mathematical modeling of deformation processes in different structural elements from steel 10Kh18N10T under radiation-induced swelling conditions showed peculiarities of their behaviour, allowing for residual welding stresses depending on the radiation dose, temperature and external load.
 
 
Keywords: radiation-induced swelling of material, radiation dose, radiation creep, residual stresses
