| 1. | In the formula , our experience in structural strength design and the experimental results are considered . and such factors are also considered as differences in materials of the skin and the reinforcer , effects of bending , torsion , stretching and offcenter of the reinforcer . furthermore , through post - buckling stress analysis of the skin , it is shown that even low stress level will result in buckling of the skin , but the skin still has loading capacity 在总结过去结构强度设计和试验分析的基础上,应用扁壳理论,在广义力与广义应变关系中考虑了蒙皮与加筋不同材料以及加筋的弯曲、扭转、伸缩和偏心等的影响,推导出适合于工程应用的加筋壳结构轴压屈曲临界载荷的计算方法;并通过对薄壁结构蒙皮后屈曲应力分析,说明蒙皮在很低的应力水平时就出现失稳现象,但失稳后的蒙皮仍具有一定的承载能力。 |
