摘　　要：根据折线形截面假设,探讨了一种计算带对称 U 形槽的弯曲平板的弹塑性局部应力和极限载荷的简单方法。文中分析了槽宽系数和槽深系数对局部应力的影响,比较了深槽和浅槽两种情况,并给出了极限载荷与弹塑性交界面的关系。According to inclining section assumption,studied a simple method for calculating local stress and limit load of a bending plate with symmetrical ∪ shaped grooves.The influence of notch width (ρ/a) and notch depth (t/a) on local stress were analyed.Comparison of both deep groove and shallow groove cases and the rela- tion of limite load with elastic-plastic interface have been given finally.
