TRANSIENT RESPONSE AND WAVE PROPAGATION IN FINITE MINDLIN PLATE
The transient wave propagation in the finite rectangular plate is investigated by the generalized ray method (GRM). The GRM has been successfully used to study the transient elastic wave transmitting in the beams and infinite layered media. In the present paper, the GRM is extended to investigate the flexural wave propagation in finite Mindlin plate. The rays propagating in the finite rectangular plate can be determined by combination of the wave solution, the shock source and the boundary conditions. From the numerical results, it indicates that transient waves propagation in the finite plate can be studied by the GRM. The early short time transient acceleration responses are very large, while the early short time transient displacement responses are very small for the finite plate subjected to the unit impulse.
