Finite Element Analysis of Inclusion Effects on High Strength Steel Cord Wire Drawing
In wire drawing of high strength steel wire for the application in tier cords,the inclusion plays the key role resulting in wire fractures.The effects of inclusion size,position and shape on wire drawing is investigated via finite element analysis in this paper.A 3D finite element model is developed to analyze the effect of inclusion position on the risk of fracture,and a 2D axisymmetrical finite element model for an inclusion at the wire center is established to investigate the effects of inclusion size and shape on wire fracture.A damage model with the consideration of stress status and plastic strain increment is used to characterize the risk of wire fracture.Finite element analysis results indicate that wire fracture is very critical to the inclusion located at wire core,and inclusion with an elliptical shape and its long axis lining well with the wire axis.Finite element analysis also proves that with the use of 7 degree die instead of 9 degree die is able to reduce the risk of fractures by about 28%.
