摘要：
Based on the analysis of a 2D model composed of rectangular blocks with deformable interlayers, it is found that the earlier model of perfectly rigid blocks is only applicable if interlayers are low rigid and blocks are rigid. Otherwise, the descriptions of dynamic disturbances in such media deviate greatly. The present paper introduces a correction for this restriction, as well as analyzes the elastic properties of blocks and their contribution to the oscillation motion.
