SIMULATION OF PROPAGATION OF DISPLACEMENTS AND VELOCITIES OF DISPLACEMENTS IN AN ELASTIC HALF-PLANE UNDER THE INFLUENCE OF A FLAT LONGITUDINAL WAVE (TRIANGULAR PULSE)
Relevance. The problem of modeling the propagation of displacements and the velocity of displacements in an elastic half-plane under the influence of a flat longitudinal wave in the form of a triangular pulse is considered. Method. To solve this problem, the equations of the non-stationary dynamic theory of elasticity are applied. A method, algorithm, and a set of programs for solving linear two-dimensional plane problems that allow solving complex problems under wave action have been developed. The Fortran-90 algorithmic language was used in the development of the software package. A quasi-regular approach is used to approximate the area under study. Results. The effect is applied in the form of a triangular pulse. The estimated area under study has a 12008001 node point. A system of equations consisting of 48032004 unknowns is solved. The displacements and velocities of displacements in three points located in an elastic half-plane are shown.
