(6) Where D is the elements’ flexural rigidity, t is the plate thickness, is Poisson's ratio of the material.
Assuming that the section dimensions and material parameters of the plate are as follows: the length is ,width is , thickness is t=0.006m, the materials of the plate is made up of steel Q235, Young Modulus , Dens ,Poisson’s Ratio .When the finite element analysis was used for analyzing the dynamic characteristics of plates, shell163 was chose for the element type, and along the length and width direction the plate was divided into elements, a total of 6161 nodes.
