带缺口空心圆轴弯曲局部应力的计算

Calculation of Bending Local Stress of A Hollow Cylindrical Shaft With Notch

本文根据球形截面假设，探讨了一种计算带环形凹槽空心圆轴弯曲局部应力的简单方法、文中详细讨论了槽宽系数（p／a）、槽深系数（t／a）和圆轴内外半径比（1／a）对弯曲应力集中系数的影响，导出了理想弹塑性局部应力的表达式．

This paper, according to spherical section assumption, studies a simple method forcalculating bending local stress of hollow cylindrical shaft with a hoop diredion u－shaped notch,and discusses the influlence of notch width factor (p/a). notch depth factor (t/a) and radius ratio(a1/a) on bending stress concentration ractor. Expression for elastoplastic local stress is given.
