Dudko O.V., Ragozina V.E. On the Motion of Shock Waves at a Constant Speed in Multimodulus Elastic Media // Mechanics of Solids. 2018. 53. P. 111-119. (WoS)
For piecewise linear models of multimodulus elastic media, exact analytical solutions of one-dimensional dynamic deformation problems with plane or spherical wave surfaces are presented. Compression-extension regimes with the appearance of a centered Riemann wave and extension-compression with formation of a shock wave are considered. As the main solution method for the compression phase, we use the method of inverse determination of the boundary condition from known information on the nature ofmotion of the shock wave. Essential qualitative differences of the solutions obtained from the corresponding classical results for linearly elastic media are especially important in the study of the dynamics of porous and cohesive granular media.
