| 摘 要： | 基于含固支边层合板的非齐次状态方程，应用增维方法，建立了齐次状态方程，给出了静力问题的解析解。这种方法对于程序的实现和数值运算稳定性的提高十分有利，在求解的过程中避免了矩阵求逆，且大大提高了计算效率。数值算例显示了本文的方法是正确的。

| Abstract: | By using the dimensional expanding,the non-homogeneous state equation which is established for composite laminates with clamped edges is converted into homogeneous equation.An analytical static solution is presented.This algorithm is not only benefit to programming and the numerical stability,but also avoids the inverse matrix calculations and improves the computing efficiency.Numerical example shows the correct of the algorithm. |
