【摘要】 应用ANSYS软件 ,对平板中心圆孔的应力集中进行了有限元分析 ,对圆孔平板在单向和双向应力条件下的应力状况进行了计算和分析 ,并将有限元结果与解析解进行比较。分析表明 ,在单向应力条件下 ,圆孔大小对平板圆孔的应力分布没有明显影响。更多还原

【Abstract】 The stress distribution of flat plate that has a hole under unidirectional stress is analyzed in terms of finite element method by ANSYS software and the distribution is shown in the form of contour plot. In addition, the stress distribution around a hole is compared with the theoretical value and the effect of the diameter to the stress distribution around a hole is discussed.更多还原
