Strain-Energy Criteria for the Destruction of Ideal Rigid-Plastic Bodies

Abstract:

The process of destruction of cylindrical samples under uniaxial tension is described taking into account changes in the geometry of the sample. An approach is formulated to determine the failure constants in the form of invariant characteristics based on standard mechanical tests under conditions of axisymmetric deformation.
