Examined the response of porous saturated medium on the comparatively low effect (for example acoustical), in such way that it is possible to neglect the removal of the solid phase (carcass). In case of such impact, the «catch type» interstices, which have one access port, partially completed by water, play a large role. Analyzed the dynamic behavior of the elements of the multilayered half-space, under conditions of the superficial unstable impact. Investigated the task of non-linear response of layer on impulse excitation. Developed and realized the algorithms of obtaining of response from the typical geological model of the coal Ukrainian regions. Product Description popup.authors popup.nrat_date 2020-04-02 Close
