Web27 de abr. de 2024 · Plastic flow localization is possibly induced by (i) the yield surface vertex effect [1, 2], (ii) dilatational plastic flow accompanying macroscopic softening due to evolving damage (nucleation and growth of voids) [3, 4], (iii) thermal softening in adiabatic or high-speed deformation , and (iv) deviations from the normality rule for plastic flow … Web13 de jul. de 2024 · Abstract— An analytical solution for high-pressure torsion of a cylindrical sample placed in a rigid gasket is obtained. The sample material is assumed to be isotropic ideally plastic. The dependence of the yield strength on pressure is taken into account. A non-associated plastic flow model is used, which includes the Tresca plastic potential …
