Abstract
The authors present finite difference algorithms for solving nonstationary problems on dynamics of elastic media and structures, and perform numerical modeling of the following applied problems: stroke on an elastic half-plane by a rigid die; shock piling; generation of a pendulum wave in a blocky medium by a local impulse effect. One of the goals of the presented modeling is driving the problem solutions with minimized influence of spurious effects inherent to numerical approximation. Finally, the authors compare the results obtained in different models of elastic media.
