DESTRUCTION OF GRANULAR MEDIA UNDER PORE PRESSURE
The researchers have modernized and used the boundary element method to calculate all components of displacement vector on a sufficiently complex surface. It is shown that under compression, given the rigid contact between grains, pore pressure induces tensile loads on the contact areas. With the increase in the loading frequency up to efficient wavelength conformable with the size of the contact area, the amplitude of the tensile loads reduces and the resonant frequencies are absent.
