应用刚度分解法对复合材料对称较厚层合板弯曲问题的分析计算进行简化。根据赖斯纳 ( Reissner)理论建立起来的控制微分方程组相当于六阶偏微分方程 ,其定解问题数学上非常复杂。采用刚度分解法可以在保证一定精度的情况下达到简化计算的目的。
The stiffness analysis of composite symmetrical thicker laminates is simplified by using the stiffness decomposition method. The governing differential equations established according to Reissner’s theory are equivalent to the sixth-order partial differential equations. The problem of fixed solutions is mathematically complicated. Using the stiffness decomposition method can achieve the purpose of simplifying the calculation with certain accuracy.
