Abstract
The stresses and the particle velocities in the soil, the loading at the obstacle, and its displacement were investigated earlier in experimental investigations of the interaction of explosion waves with obstacles [1–4]. Below we present the results of experimental investigation involving simultaneous measurement of stresses and strains of soil during the passage of incident and reflected waves and also of the loading at the obstacle. This permitted us to refine the characteristic features of the primary and secondary compression of the soil and to verify the applicability of the model of an elastoplastic medium [4].
