Abstract: | We consider a numerical solution technique for generalized axisymmetric problems with torsion for elastoplastic bodies of
revolution of arbitrary shape under large strains, as well as simple or complex loading, and the conditions of inhomogeneous
stress-strain state. The processes of elastoplastic deformation, strain localization, and fracture of solid axisymmetric steel
samples of variable thickness are studied experimentally and numerically for the cases of proportional and nonproportional
kinematic torsional and/or tensile loading until failure. The mutual influence of torsion and tension on the deformation and
failure under large strains is estimated. |
