本文采用修正的Hahn-T sai非线性本构关系,应用加权残值法,以三角级数一五次样条为试函数,计算了承载边简支,另二边为不同支承的反对称角交层板的非线性稳定问题。由于至今谨见到该问题在四边简支条件下有解,因此本文方法大大扩展了这类问题的研究,而且方法可靠。本文以大量数例讨论了材料非线性对不同铺设角、不同层数和不同宽厚比在不同边界条件下的临界载荷的影响,得到了许多有意义的结论。
In this paper, a modified Hahn-T sai nonlinear constitutive model is used. By using the weighted residual method and the trigonometric series of fifth-order spline as the test function, the simple symmetry of support is calculated and the antinodisymmetric angles of different supports are calculated on the other two sides Nonlinear stability of cross-ply. Since we have seen so far that the problem has been solved under the simple support conditions of the four sides, the method in this paper greatly expands the study of such problems and the method is reliable. In this paper, we discuss the effects of material nonlinearities on the critical loads of different laying angles, different layers and different aspect ratios under different boundary conditions with a large number of examples. Many meaningful conclusions are obtained.
