Abstract: The real equation of state of materials is different from that of metals in the computation of explosion mechanics,due to its complicated material construction. The paper places the emphasis on the description of the real equation of state of materials. In terms of the physical mechanics and the semi-empirical-semi-theoretical method the description can be made as follows: 1) The equation of state is derived from the usual thermodynamics method, and some parameters are calculated with the help of experiment...
