The Use of the Ring Compression Test for Defining Realistic Metal Processing Parameters

摘要

The ring has been shown to be a very versatile tool for studying realistic metalworking processing parameters. Computer solutions of mathematical analyses made of ring compression have been verified by experimental tests, have increased the accuracy of the original purpose of the ring test for determining quantitative friction measurements under processing conditions and have provided a method for optimizing the geometry for friction studies. The solutions have also been applied to the determination of true stress-true strain compression curves for deforming materials under processing conditions. These curves provide flow strength data required for computing deformation loads in metalworking operations and serve as a reference base for metalworking workability studies. (Author)
