The Effect of Radial Inertia on Combined Plastic Stress Wave Propagation in Thin-Walled Tubes

Abstract

This investigation is concerned with the analysis of combined longitudinal and torsional inelastic stress wave propagation in thin-walled tubes. The effects of radial inertia are included in the development of the governing hyperbolic differential equations which are solved by the method of characteristics. Numerical results are presented for combined stress wave propagation in statically preloaded tubes of material assumed to be described by rate-independent plasticity. The effects of finite rise time of the imposed dynamic load and of radial inertia are analyzed in detail.
