Natural Frequency for Rectangular Orthotropic Corrugated-Core Sandwich Plates with All Edges Simply-Supported

摘要: 给出了一种把具有波纹型夹心的正交各向异性夹层板的控制方程组化为仅包含一个位移函数的单一方程的简单方法,从而获得了在四边简支条件下其自由振动固有频率的精确解。同时还对两种具有重要实际意义的特殊情况进行了讨论。

Abstract: A simple approach to reduce the governing equations for orthotropic corrugated-core sandwich plates to a single equation containing only one displacement function is presented, and the exact solution of the natural frequencies for rectangular corrugated-core sandwich plates with all edges simply-supported is obtained. Furthermore, two special cases of practical interests are discussed in details.
