The most prominent feature of sheet metal forming process is an elastic recovery
phenomenon during unloading which leads to spring-back and sidewall curl. Accordingly, it …

Heat transfer continues to be a major field of interest to engineering and scientific
researchers, as well as designers, developers, and manufacturers. The wealth of …

Sheet metal extrusion is a process in which the extrusion punch penetrates one surface of
the sheet metal material to cause it to extrude and flow toward the outlet of the die. In fact …

Servo press technology is gaining attention because its punch motion curve offers greater
formability than that of a conventional stamping press. This study investigated the effect of …

This paper dwells on the nature of the highly non-linear interactions occurring during heat
treatments with the aim of developing an improved understanding of the process and of the …

Flow stress is an essential material property for metal forming. A stress–strain (SS) curve is
generally measured by tensile testing or compression testing. In some metal forming …

Hot metal forming (rolling, forging, extrusion, wire drawing) constitutes a very large
proportion of manufacturing activity. Of all the equipment and tooling involved in a hot …

Recently, a high pressure torsion testing method was developed to measure stress-strain
curves in a super large strain range, eg over 10. In this paper, through improvement of the …
