In the present paper, a tensile elastic-plastic-viscoplastic constitutive equation is proposed where the concepts of under-stress and over-stress is introduced. Strain-rate-dependence of stress, high strain-rate-dependence of stress, strain-dependence of wave propagation speed and strain-rate-dependence of wave propagation speed are shown. 1-dimensional numerical analysis of a bar subjected to longitudinal impulsive loading is carried out using the constitutive equation proposed. As a result, the existence of the strain plateau in the strain-distance plane, the existence of constant strain and the attenuation in the strain-time plane, strain-dependence of wave propagation speed and strainrate-dependence of wave propagation speed are shown.
