摘要：
The formulas for the correct evaluation of dynamic stresses in structurally anisotropic plates are deduced by using the polarization-optical method and the basic relations of photoelasticity. We study the wave field of stresses formed in an anisotropic plate loaded on its free boundary by pulses from a point source and the influence of anisotropy on the character of the analyzed field. The distribution of dynamic stresses induced by a concentrated source is investigated and the dependences of the maximum stresses in quasilongitudinal -waves and Rayleigh waves on the distance from the source are established. © 2004 Plenum Publishing Corporation.
