To develop a methodology for the calculation of residual stresses in the area of composite welded joints, it is planned to use modern advances in deformation mechanics, in particular, elastic-viscous-plastic deformation of structural materials under non-isothermal conditions, taking into account the complex load in space and time, as well as the achievement of computing and numerical methods Product Description popup.authors Velikovanenko Elena А.
