Forming Limit Diagram, Void Analysis, Strain Distribution and Surface Roughness for SS430 Sheets During Multipoint Incremental Forming [PDF]
Single point incremental forming process is a most economical Die-less forming process. The major constraint of it is that it is a time consuming process. In this work, a new attempt was made in incremental forming process using Multipoint tool for SS430

A cruciform shape to study the influence of strain paths on forming limit curves [PDF]
International audienceThe optimization of sheet metal forming processes requires an accurate prediction of material behavior and forming abilities, especially for aluminum alloys which exhibit generally a low formability compared with typical mild steels.

Forming Limit Diagrams of Perforated St12 Steel Sheets [PDF]
Abstract One of the unique characteristics of sheet metals is their formability, which is determined by the forming limit diagrams. These diagrams specify the maximum deformation limit before part’s failure. For several applications of metal sheets, they have to be in the perforated format.

Modeling the transient flow of undercooled glass-forming liquids [PDF]
n a recent experimental study on flow behavior of Vitreloy-1 (Zr41.25Ti13.75Cu12.5Ni10Be22.5), three distinct modes of flow are suggested: Newtonian, non-Newtonian, and localized flow.

The Forming Limit Diagrams of a Brass Sheet
The forming limit diagrams of proportionally pre-strained brass sheets are experimentally determined for a combination of uniaxial and equi-biaxial tension. From these FLDs and the theoretical ones which are predicted by the use of a new plastic constitutive equation previously proposed by one of the authors (Gotoh) and a local necking condition, the ...
