Vibration of a system of massive stamps on a linearly deformable foundation
A variational-difference method is applied to solve dynamic contact problems with contact domains of arbitrary planform, where the tedium in realizing this method is reduced substantially while the convergence is improved by the selection of delt-like functions of a special kind as coordinate functions. Results of numerical investigations are presented for the vibrations of a system of massive rectangular stamps on an elastic bed. The presence of resonance frequencies whose values depend on the size and mass of the stamps, and the presence of a shielding effect when a surface wave runs over the system of stamps are clarified.
