| 摘 要： | 本文把缩减弯曲刚度法推广应用于具有不同拉压模数的层板,并且提出了一种求解具有不同拉压模数的层板问题的新的近似方法——二次近似法。这三种方法应用于具有不同拉压模数的正交层板柱形弯曲近似计算,与解析解相比,误差不超过10％。

| Abstract: | The reduced bending stiffness method is extended to laminates with different moduli in tension and compression, and a new approximate method-twice-approximate method is presented in this paper. The two methods are applied to approximate calculations of cylindrical bending of cross-ply laminates with different moduli in tension and compression. In comparison with the analytical solutions the results are not beyond 10 percent |
