Abstract This contribution presents preliminary data on the petrographic and mineral—chemical composition of granitoid dioritoid core samples Itatsky Kamenny sites in Nizhnekansky Massif Krasnoyarsk Region, combination with structure their pore space, filtration, elastic, mechanical thermophysical properties, necessary to select a site for an underground research laboratory. laboratory would be precursor radioactive waste facility. It was found that variation petrophysical properties depends...
The problem of determining the two-dimensional dynamic stress state near a tunnel defect V-shaped cross-section is solved. located in an infinite elastic medium, where harmonic longitudinal shear waves are propagating. initial reduced to system two singular integral or integro-differential equations with fixed singularities. A numerical method for solving these systems regard true asymptotics unknown functions developed.
An elastic isotropic body in a state of plane deformation, which contains system randomly placed cracks under the action dynamic (harmonic) loading, is considered. The authors set problem determining stress field around conditions their wave interaction. solution method based on introduction displacements form superposition discontinuous solutions equations motion constructed for each crack. With this mind, initial reduced to singular integro-differential with respect unknown displacement...
An effective analytical-numerical method for determining the dynamic stresses in a hollow cylindrical body of arbitrary cross-section with tunnel crack under antiplane strain conditions is proposed. The allows separately solving integral equations on faces and satisfying boundary boundaries. It provides convenient numerical scheme. Approximate formulas calculating stress intensity factors neighborhood are obtained influence geometry wave number these quantities investigated, especially from...
