On the Optimum Die Shape in Rod Drawing Process Considering Work-Hardening Effect of Material

The assessment of the influence of the work-hardening of material on the optimum die profile and drawing force  in rod drawing process is the main objective of the present paper. The upper bound solution, based on the assumption of perfect plasticity, has been extended to consider the work-hardening of the material during the rod drawing process through curved dies. Analytical results of drawin...

On the optimum die angle in rod drawing process considering strain-hardening effect of material

In this paper, rod drawing process of strain-hardening materials is investigated by analytical, numerical and experimental methods. The classic upper bound solution, based on the assumption of perfect plasticity, has been extended to consider the work-hardening of the material during the drawing process. For a given process conditions and mechanical properties of the rod material, the power ter...

The "right to die": on drawing (and erasing) lines.

analytical evaluation of the effect of die and punch profile radii on deep drawing force

in this study, the formation of different parts of a cup during deep drawing process has been investigated analytically using the geometrical relationships. for a given punch travel, the effects of the bending angle, and those of the die and shoulder radii on the flange and die shoulder strains were examined. in addition, different components of the deformation force were calculated and the pun...

Report on the 1st Indian Cancer Congress 2013

The 1st Indian Cancer Congress (Delhi, 21-24th Nov) has been a reminder that the world of cancer is not all about the ASCOs and the ECCOs. What made this conference arguably more impactful and important globally than most others, was its relevance not just for India but also for many other emerging and low-income economies. Most cancer patients will live and die far away from high-income system...
