| 摘 要： | 本文采用四结点20自由度的矩形板单元,对任意铺层层合板的弯曲-拉(压)耦合问题进行了有限元分析,计算出板的位移、内力、应力,应变和极限荷载.其计算程序适用性较广,也可用于各向同性板的弯曲-拉(压)耦合问题.对文献中的一些算例进行了计算,计算表明,对于非对称铺设的层合板,耦合作用不能忽略.对钢丝网水泥平板以及钢丝网水泥/玻璃钢复合的层合板除计算外,还进行了试验,二者结果较为一致.试验还表明,复合层合板的承载能力较之钢丝网水泥板的承载能力大为提高.

| Abstract: | In this paper, the rectangular plate element with 4 nodes 20 freedoms is adopted to perform finite element analysis of bending/stretching cupling of arbitrarily laminated plates and the displacement internal force, stress, strain and limited load of the plate are calculated. The program provided in the paper can also be applied to the bending/stretching cupling of isotropic plates. Several examples have been chosen to investigate the accuacy of the element suggested in this paper. Computations show that the cupling effect is not negligible for unsymmetrically laminated plates. Ferrocement plates, ferrocement/glass fiber reinforced plastics laminated composite plates are also calculated, and the results are compared with experimental results. The comparsion shows that the load carrying capacity of the latter is much larger. |
