R&D Update: The importance of the n value in sheet forming

October 11, 2001

By:

Strain hardening is represented by the exponent n in the flow stress equation, which approximates the relation between true stress and true strain during plastic deformation of a metal. The constant n plays a crucial role in sheet metal forming, and this brief article describes its effects.

Successful tube hydroforming: Watching parameters, accurately simulating the process yield good results

June 15, 2001

By: ,

A typical tube hydroforming system is shown in Figure 1. Within this system, a host of factors must be taken into account, from starting tube geometry and material properties to the quality of the final part (such as thickness distribution and dimensional accuracy).
