The strain-stress relationships of the materials are achieved by processing the pulse signals.
The J-C model is adaptable to the dynamic impact behaviors at high strain rates of materials.
For metal materials with high plastic strain rates, η is 0.9, Cp is heat capacity at constant pressure, Cp is nonlinear, Cp of metal could be reducible to a linear relationship which is indicated by the formula below
