An asymmetric tangential load on the boundary of an elastic half-space

Investigation of wave processes in a rectangular region with discontinuous boundary conditions

“…From a comparison of the oscillograms of the normal stress p + q (Fig. 2), it can be seen that the stresses at points 1, 2, 3 appear simultaneously and at the initial stage of the change, on the whole, repeat profile of the loading specified by the boundary action (6). A significant increase of the amplitude p + q at points 1, 4 and a decrease in the maximum compressive stresses at points 3, 6 are due to the different nature of the reflection of the load wave from the fixed and free sections of the strip boundary h x 100 1 =…”

“…The computational process is carried out in time steps. The time step k is selected in accordance with the necessary stability conditions of used explicit finite difference scheme [6] The study of stability has shown that the grid ratio k/h equaled 0.5, provides stable results for a sufficiently large time interval under multiple reflections and diffractions of waves. In fact, the calculation was carried out to t = 600k.…”

“…In connection with rapid growth of modern computing facilities and modern information technologies, there is also a necessity for their use for solving problems of these kinds and obtaining working programs for personal computers which allow to calculate a particular state of objects in concrete problems of practical direction [сf. [1][2][3][4][5][6][7].The purpose of this study is to develop a difference method of spatial characteristics for solving plane problems of dynamic elasticity with discontinuous boundary conditions.…”
