Objetivo The main objective of this project is to investigate the air shock wave interaction with an obstacle covered by a porous material in wide range of defining parameters of a wave and porous material. For developing the comprehensive theory of this process reliable experimental data is needed. Experiments on a vertical shock tube will be performed on air shock wave interaction with the end wall of tube covered by a porous material. Gas pressure and total stress profiles will be measured before a porous layer, within the layer and after the layer in the air pocket and at the end wall. The effect of the waveform, the size of particles, type of material and length of porous layer on the wave process will be studied. On the base of this experimental data parameters of mathematical model will be selected. Constitutive equation for the skeleton will be developed. The shock tube experiments will be numerically simulated. The effect of the air pocket length, friction of the porous material with the wall of the tube, compressibility of tube walls, interphase heat transfer, mobility of granules, non-linearity of wave process will be studied. As a result of this simulation numerical code will be elaborated.Linear and non-linear, one- and two-dimensional theory on the base of mechanics of multiphase media will be developed. The effect of defining parameters of wave and porous screen on shock wave damping and amplification will be investigated. Conformities to natural laws of air shock wave interaction with an obstacle covered by a porous screen will be determined. This knowledge makes it possible to control the impact of a shock wave on an obstacle by means of installing a porous screen with definite parameters to achieve the damping as well as amplification of the impact.
