Prediction of central bursting in the process of forward extrusion using the uncoupled ductile failure models
Original language description
Forward extrusion is a manufacturing process in which the cross section of product is reduced by forcing it through the die under high pressure. Cold extrusion is most often used in the mass production of cylindrical rods or hollow tubes due to its economic advantages, although it can be used for more complex shapes of cross section. The process is accompanied by excessive amount of plastic deformation and central burst defects, the so-called chevron cracks can occur. These defects are dangerous because of their invisibility on the product’s surface. Therefore, it is important to carry out computational simulations to successfully predict and prevent the central bursting. Solution of this problem is especially influenced by the die cone angle, friction and reduction ratio. In this study, the process is analysed through numerical simulations using the uncoupled ductile failure models which were calibrated and implemented into Abaqus/Explicit by user subroutine VUMAT. Obtained results are compared to experiments conducted on the carbon steel AISI 1045 and predictive potential of the criteria is discussed.
