各向同性刚度矩阵层

各向同性材料的每层的局部刚度矩阵

d_{i}' = [\begin{matrix} d'_{11, i} & d'_{12, i} & 0 \\ d'_{22, i} & 0 \\ s y m . & d'_{33, i} \end{matrix}] = [\begin{matrix} \frac{E_{i}}{1 - ν_{i}^{2}} & \frac{ν_{i} E_{i}}{1 - ν_{i}^{2}} & 0 \\ \frac{E_{i}}{1 - ν_{i}^{2}} & 0 \\ s y m . & G_{i} \end{matrix}] i = 1, . . ., n m i t G_{i} = \frac{E_{i}}{2 (1 + ν_{i})}
