At experimental researches of interaction shock-wave loads with various types of physical objects the effects were found out, qualitative and which quantitative interpretation managed to be found within the framework of representations of the mechanics of multiphase systems. In a series works about research of interaction of shock waves with thixotropic the media, high viscosity non-Newtonian and Newtonian by liquids revealed the physical mechanism of effect of abnormal amplification (strengthening) of shock waves. The amplification (strengthening) is caused by interaction of shock waves with formed at consecutive loadings by a layer a bubbles. The effect of repeated reduction of time of clearing of a polymeric solution from bubbles of gas is found out at cyclic processing shock loadings. At influence of shock waves on viscoplasticity of media the effect of change of a limiting pressure (voltage) of shift is found out. At imposing shock-wave loadings on the process of filtration in core with a residual not mixing up phase is found out effect of peak increase of the charge of a filtered liquid.
