Abstract:
Numerical algorithms simulating the dynamic interaction of elastic blocks
through thin viscoelastic interlayers in structurally inhomogeneous media
such as rocks are proposed. On the basis of the rheological method, the
models of various levels of complexity describing the deformation of a material
of interlayers are constructed. When solving the one-dimensional problems
numerically, the monotone grid-characteristic schemes with a balanced number
of time steps in blocks and in interlayers are applied. The software implementation
of algorithms for multiprocessor computer systems with graphics accelerators
is discussed. The numerical results illustrating the qualitative features
of the plane wave propagation in materials with a layered microstructure
are given.
