Center bursts - a review of criteria

摘要

The development or exacerbation of centerline fractures and porosity in wiredrawing has been the subject of many analyses, especially owing to the liabilities regarding drawing breaks and cable and fastener failures. A number of criteria are set forth in technical literature, with rather different treatments of the roles of ductile fracture resistance and pre-existing centerline flaws. This paper presents a modern review and consolidation of the engineering criteria for center bursting in the drawing of rod and wire.
