摘要: The early short time transient response of an L-shaped plate is investigated by the method reverberation ray matrix (MRRM) and generalized (GRM). MRRM GRM have been successfully used to study elastic wave transmitting in beams, planar trusses, space frames infinite layered media. In present paper, these two methods are extended investigate flexural propagation a finite Mindlin plate. reverberation-ray representing multi-reflected scattered waves presented. rays propagating determined shock source boundary conditions. From numerical results, it indicates that responses calculated same as those GRM. acceleration very large, while displacement small for subjected unit impulse. Furthermore, effects different signals thickness on plates also analyzed.
