%X An experiment equipment of triaxial dynamic compression is used.Measurements of domestic Comp. B have been made in triaxial compression as a function of temperature and strain rate. Young's moduls, yield strenghth and Poisson's ratio have been obtained. The experiment results show that there is clear temperature and strain rate dependence in Comp. B. The Young's modulus and yield strength of Comp. B are larger than those of TNT. Based on the thermally activated theory a plastic flow constitutive model is suggested. The results of analysis indicate that by the constitutive model the strain rate and therm effect of Comp. B are properly described.
