AbstractAnalytical results are presented for the dynamic interaction of an elastic flexural plate and an elastic half‐space subjected to harmonic seismic waves. Displacements and contact stresses are presented for square, massless plates having a practical range of flexural stiffness and subjected to incident waves oriented parallel to either an edge or a diagonal of the plate. The behaviour of massive plates is also briefly discussed; such plates exhibit additional resonances higher than those normally associated with the motion of a rigid mas
