摘要
本文对大高度、软夹芯的复合材料夹层板的弯曲问题,提出了一种新的修正的Reissner理论。该理论对Reissner的线性特性进行了非线性修正;引入夹芯弹性支撑作用对变形与应力的修正。修正项由Reissner理论结果确定,并最终归结为求解Reissner理论问题,使计算更精确而应用亦较方便。
Most composite sandwich plates have cores with finite compressed modulus (i.e. Ez0≠∞). A new revised theory for Reissner model has been developed to solve the bending problem of composite sandwich plates with thick and soft cores, in which two aspects of revision to Reissner theory have been done as following.a.Revision of displacement from linear assumption to non-linear one;b.Revision of stress and deformations caused by the elastic supporting of the soft core.The terms of revision are determined by the Reissner theoretical results, and the problem to be solved is reduced to the solution of Reissner theory, which makes the computation more accurate and convenient.new revision of Reissner theory, composite sandwich plate, thick and soft core, bending
