Abstract:
New numerical algorithm for free-flowing media dynamic analysis is constructed on
the basis of constitutive equations of multi-modulus elasticity in terms of variational
inequality with constrained stress state. Numerical results in Riemann problem of
shock decomposition are compared with exact solutions. In two-dimensional case the
process of loading and unloading waves propagation with the appearance of connecting
discontinuities is considered. By means of numerical modeling the picture of “dry boiling”
under the action of periodic perturbation is obtained.
