本文提供了一篇用有限单元混合法对开孔补强的圆柱壳进行应力分析的报告。作为试验研究我们用了三向光弹性技术。通过比较发现由有限单元混合法得到应力分析的结果相当接近于光弹性试验结果的。并且证明开了孔的圆柱壳局部补强是有效的,它使结构的强度和刚度有显著的增强。此外,用有限单元混合法对于开孔但不补强的圆柱壳进行分析所得结果与经典理论结果也是相当一致的。 This paper provides a report on the stress analysis of open-pored cylindrical shells using the finite element mixing method. As a test study we used three-way photoelastic technology. By comparison, the results of the stress analysis obtained by the finite element mixing method are quite close to those of the photoelastic test. And it is proved that the local reinforcement of the opened cylindrical shell is effective, which makes the strength and rigidity of the structure significantly enhanced. In addition, the analysis of the open-hole but non-reinforced cylindrical shell by the finite element mixing method is also quite consistent with the classical theoretical results.
