Combined plastic simple waves in a thin-walled tube

摘要

Constitutive relations for adiabatic rate-independent materials processes with combined isotropic-linear hardening finite deformations are used to study the problem of a thin-walled cylindrical tube subject to combined longitudinal and torsional impact at one end. The effect of transversal inertia is disregarded but that of transversal motion is taken into account. Influence of the plastic spin on the problem is discussed. A numerical solution for stress trajectories of simple adiabatic waves is provided.
