| 摘 要： | 由各向同性材料构成的构造上各向异性板,如正弦波纹板,当板厚达到一定数值时,Seydel的第二主向刚度公式不再适用。依据平板的抗弯刚度公式,提出等效惯性矩的思想,构造适应较厚波纹板的第二主刚度公式。通过对四边简支的波纹板的计算和实验测量,证明在板较薄时Seydel的公式较适用,而当板厚尺寸增加到一定值时,文中给出的第二主刚度公式接近实验值。

| Abstract: | For the structurally anisotropic plank made by isotropic material,such as sine corrugated plate,the secondly main stiffness formula of Seydel is not applicable when the thickness of plate increases to the certain value.According to bending stiffness formula of the flat plate,the new idea of equivalent inertia moment is proposed,and the modified secondly main stiffness formula for corrugated plate is obtained.The experimental measurement results are compared with the present theoretic prediction on simply su... |
