| description | In this paper the influence of an eccentric inclusion and cavity on copper shaped-wire
drawing were investigated. An experimental investigation for optimal die half-angle
was conducted. Based on experimental data of optimal die half-angle, the
deformations, the mean normal stress and the plastic strain of both copper shapedwires
containing an eccentric inclusion and cavity were calculated by finite element
analysis. The same parameters for both copper shaped-wires containing a centric
inclusion and cavity were also calculated using the same method. Necking, bending
and misalignment were observed during drawing of a wire containing an eccentric
inclusion. However only necking was observed during drawing of a wire containing a
centric inclusion. It was found that the inclusion rotated during drawing and extremely
compressive stress occurred on the die contact surface during drawing of wire
containing eccentric inclusion. For the same inclusion size, the drawing stress was
strongly .influenced by inclusion size and slightly influenced by eccentric length. The
drawing stress of wire containing centric inclusion was greater than that of wire
containing eccentric inclusion. It was found that the drawing stress decrement was due
to- a cavity and the deformation behaviour of a wire containing a cavity was opposite
to that of a wire containing an inclusion |
