余热处理钢筋横肋根部冷弯裂纹的有限元分析

运用ANSYS有限元分析软件，对余热处理钢筋横肋根部应力状态进行了数值模拟分析，得到了余热处理钢筋横肋根部冷弯裂纹产生的原因并提出了相应的改善措施。

Using ANSYS finite element analyzing software, numerical model analysis is made on the residual state in the transversal rib root part of residual heat treated ribbed bar, so that the reasons causing cold bending cracks in transversal rib root part are work out and corresponding improvement measures put forward.
