尽管已有文献对圆柱壳的屈曲性能进行了大量研究,但对物理接触引起的局部大型缺陷的影响尚未进行深入研究。为此,对均匀围压下局部凹陷薄圆柱壳的屈曲和后屈曲响应进行了试验研究。研究结果可以在实际工程中与其他类似几何特性(如径厚比)共同应用。
Although a large number of studies have been conducted on the buckling behavior of cylindrical shells, the influence of physical contact on large local defects has not been studied further. For this reason, the buckling and post-buckling response of partially hollow cylindrical shells under uniform confining pressure were studied. The results of the study can be used in conjunction with other similar geometries (such as diameter to thickness ratio) in practical engineering.
