The constitutive equations are formulated from the rate dependent mechanical models which express the elastic-viscoplastic and the elasticviscoplastic-plastic materials. Wave propagations are analyzed for the one dimensional stress bar experiment by using the constitutive equations. Comparisons are made for the stress as well as the strain with the experimental data. It may be concluded that annealed copper possesses both noninstantaneous and instantaneous plastic properties.
