To investigate the constitutive relation between the stress, strain rate and temperature, longitudinal compressive impact and quasi-static tests are made at various temperatures with cylindrical specimens of annealed copper. Experimental results of impact tests are compared with the analytical results calculated by using the Malvern-type constitutive equation proposed previously by the authors. The results in the temperature range examined in this study are discussed on the basis of the theory of constitutive relation proposed previously by the first author. Consequently, the constitutive relation of copper in the region from quasi-static strain rate to high strain rate can be explained by dividing the fields into three, each of which satisfies our constitutive equations, and two boundaries among the three fields measured on the quasi-static strain rate region extend continuously to the high strain rate region.
