Title:
Numerical study of an influence of material constants of a heteromodular elastic medium on solutions of plane self-similar problems of shock deformation
The paper presents the results of numerical solving 2D self-similar problems of the dynamic deformation of rocks under plane strain conditions. To describe the dynamic behavior of materials in question under the action of a shock load, a model of an isotropic-elastic heteromodular medium with a singular dependence between stresses and deformations is chosen. A series of computational experiments was carried out for various materials and parameters of the boundary conditions. As a result, it has been concluded that the sign of the material constants responsing for the manifestation of different modularity in the model equations has a significant effect on the solution as a whole and the behavior of the arising deformation waves in particular.
