摘要
由于复合材料层合板的横向剪切模量较低,因此基于克希霍夫理论而计算的层合板特征问题及其灵敏度与实际情况相差较大。本文采用层合板的一阶剪切变形理论,将纤维铺设角、材料参数和从中面到第K层板上表面的距离Zk-1视为设计变量,研究了对称层合板特征值和特征向量的灵敏度计算问题。
Laminated composite plates having a relatively low transverse shear modulus, Kirchhoff theory has proved to be inadequate for calculating the eigenproblems and sensitivity of laminated plates. In this paper the first-order shear deformation theory is applied to symmetrically laminated plates. The orientation angles of the fibers, material parameter and the vectorial distance from the middle-surface to upper surface of each ply are taken as design variables in the study of sensitivity of eigensolutions for the symmetrically laminated plates.
