Abstract:
The aim of this work is numerical simulation of wave propagation in media with linear-elastic and acoustic layers. As an example the seismic exploration in the Arctic and the explosive impact of an iceberg had been simulated. The complete system of equations describing the state of a linearly elastic body and a system of equations describing the acoustic field are solving. The use of the grid-characteristic method provides correctly describing the contact and boundary conditions, including the contact condition of between acoustic and linear-elastic layers.
