| Abstract: | In this paper, random responses of thick plates are analysed by using the vibration equation of elastic thick plates with external and inner damping, deduced by the author here. The thick plates in it are regarded as continua. Loads are described by random functions. Analytical expressions for dynamic characteristic of thick plates and general expressions for random responses of thick plates are given. Numerical results for rectangular plates as example are given herein. The results are compared with those obtained from the improved theory and the classical theory. |
