Musaev V. K., Nemchinov V. V.

In the article the authors propose explicit time-numerical method for solving dynamic elastic problems, based on approximation of the right-hand sides of differential equations by the finite element method, but the definition of velocity and displacement on the following temporary layer is defined taking account the linear velocity distribution between the layers. The method has the regulated approximation viscosity and dispersion of the numerical solution. We studied the accuracy and convergence of numerical solutions for the dynamic problem of diffraction of a longitudinal wave in a spherical cavity.
