Maximum Hydrostatic Stress Analysis of Multi-Pass Inclusion Copper Wire Drawing by FEM
Keywords:
Multi-pass drawing, internal fracture, wire fracture, FEM, copper shaped-wire, inclusion, hydrostatic stressAbstract
The size and length effects of inclusion on multi-pass copper shaped-wire drawing were investigated. The wire and inclusion deformations and hydrostatic stress of copper shaped-wires that contain an inclusion were calculated by two-dimensional finite elemental analysis. During drawing if a wire contains an inclusion, a necking occurred. The effects of inclusion size and length on maximum hydrostatic tensile stress in front of inclusion during multi-pass copper shaped-wire drawing were carried out. The maximum hydrostatic tensile stress appeared on the wire centerline in front of the inclusion for single-pass drawing. For multi-pass drawing, the maximum hydrostatic tensile stress was located at both sides of the wire centerline in front of the inclusion. Symmetrical double cracks easily originated in those regions.
