Аннотация:In this study, a modified anisotropic elastic Weiskopf model for a sandy medium was introduced, satisfying the highest rotational symmetry compatible with a Weiskopf sandiness parametergreater than the unity. The developed approach was applied for computing and comparing head SPwaves propagating along the free surface of the halfspace. The comparison revealed a substantialdiscrepancy in the SP wave pulses detected at the points of observation. The developed models forthe generation and detection of SP waves are based on the FEA (finite element analysis) of the innerLamb problem.
