Abstract:

A calculation model was developed upon the elastic theory and the complex function theory. According to the calculation model, both of the stress field and that of the area near the hole edge can be analyzed. Some instructive conclusions were drawn. Comparisons were made on the stress components,and comparisons on the stress field were made when the distance away from the aperture changed. The influences of different loads and different distance away from the hole-edge on the stress field were explored.

Key words: plate with circular hole, hole-edge stress field, different kind of load, stress field at different distance away from hole-edge, simulation

摘要：

建立了基于弹性理论及复变函数理论的计算模型。利用所建立的计算模型对孔边应力场进行了分析，同时也对孔口附近的各应力分量进行了较为全面的计算，得到了一些有益的结论。对孔边各应力分量进行了比较，同时也对距孔边不同距离时的应力场进行了比较。另外，通过施加不同的荷载，对孔边的应力场以及距孔边不同距离时的应力场的影响进行了研究。
