    Abstract
  • The deformation and spalling behavior of the cylindrical steel tube under external explosive loading was studied. On the basis of the damage evolution equations and considering damage and temperature softening effects, we obtained the explicit plastic constitutive relations. Numerical simulations were carried out and the computational results were analyzed. The satisfactory agreement between the computational results and the experimental ones shows that the constitutive relations and computational method presented in this paper are reasonable and of important in practical usage.
