摘要
本文以薄圆柱壳大开孔应力集中问题的理论解为基础，利用保角映射方法对圆柱壳非圆大开孔的应力集中问题进行研究。在给出映射函数的基础上，对承受不同外部载荷下开椭圆大孔圆柱壳孔边应力集中系数进行了数值计算，并与相应的圆柱壳小开孔理论解进行了比较。结果表明：大开孔解答更具有合理性。
In this paper, conformal mapping is employed to study the stress concentration on thin cylindrical shells with large non-circular openings. Based on the theoretical solutions of thin cylindrical shells with large openings, the mapping functions are obtained for non-circular and non-elliptical cutouts. Numerical results for free elliptic cutouts with different opening ratios and different external loading conditions are obtained and compared with available solutions based on small opening theory. It is shown that the solutions of stress concentration based on large opening theory are more reasonable.
