四边转角约束正交异性板的临界载荷

摘要

考虑横向剪切变形的影响和四边弹性转角约束的边界条件，给出了一种求解正交异性板临界应力的方法. 弹性转角约束的极限情况就是简支和固支. 应用本文给出的方法，在几种退化的情况下，对若干矩形板进行计算，并与现有文献进行了比较，结果吻合较好，从而验证了文中给出的方法.%A method for calculating the critical stress of shear deformableorthotropic plate with four edges elastic angle constrained is proposed.Simply-supported and clamped-supported are two limiting situations. With this method,critical stresses of several kinds of rectangular plates are calculated in somedegenerated cases. The comparison with other references shows good agreement,which verifies this method.
