| 摘 要： | 研究两端固支层合复合材料浅拱在均布载荷作用下的非线性稳定性，首先利用文献１得到的层合浅拱在非线性几何大变形假定下的动力学控制方程，包略其惯性项，得到层合浅拱在均布载荷作用下的平衡微分方程，然后由修正迭代法对两端固支情况进行了求解，从而得到了几种销层情况下的临界载荷；最后对计算结果进行了讨论。

| Abstract: | In the paper, the non linear stability of a two end clamped laminated shallow arch under uniform distrabuted loads is investigated. Based on the hypothesis of geometrical large deform, using the equations in after neclected the inertia term, the equilibrium differential equations of the arch under uniform distributed loads are derived. Then, it is solved for the two ends clamped boundary conditions by modified iteration method.Thus, thecritial loads of the arch in several ply direction of fabric of laminating are obtained. At last, the computational results are discussed. |
