| 摘 要： | 本文用最小二乘配点法分析带有圆孔的圆柱壳在轴向拉伸、扭转或内压力载荷作用下的应力状态。对于较小曲率参数的情况,其解与某些解析解和实验结果比较,相当符合。该法易于推广到更复杂的问题,如各种形状的孔口或加强孔。

| Abstract: | This paper suggests the use of the least square collocation method to ana-
lyse the state of stress in a cylindrical shell containing a circular cutout under
axial tension, torsion, or internal pressure loading. The results are compared
with the solutions obtained by more rigorous analytical methods and with some
experimental results. For small values of the curvature parameter, the agreement
is good. The method appears to be readily extended to more complex problems,
such as cutouts of various types with or without reinforcement. |
