A generalization is made of the results of experimental investigations into the elastoplastic deformation of initially isotropic structural materials with a stable and metastable structure loaded along rectilinear and slightly curved paths. It is revealed and physically substantiated why some hypothesis of plastic theory, which are valid for materials with a stable structure, are not fulfilled for deformationally unstable metals. It is indicated how much the study results can be used in calculations and to improve the technology of manufacturing thin-walled shell structural elements by optimizing their strength, plasticity, and crack resistance [ABSTRACT FROM AUTHOR] |
