Forming Limit Diagram, Void Analysis, Strain Distribution and Surface Roughness for SS430 Sheets During Multipoint Incremental Forming [PDF]

open access: yesArchives of Metallurgy and Materials, 2018
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

An effective method for determining necking and fracture strains of sheet metals

open access: yesMethodsX, 2021
Biaxial tensile testing methods using cruciform specimens have been developed in the last few decades for the determination of forming limit diagrams (FLDs) and fracture forming limit diagrams (FFLDs) for sheet metals.

Forming limits of austenitic stainless steel sheets [PDF]

open access: yesComputer Methods in Materials Science, 2006
The forming limits of austenitic stainless steel sheets were studied. It was found that the observed limit of straining in stretch forming, when both of the principal stresses are positive, is not set by localized necking, but instead by shearing ...

Experimental analysis for defining forming limit diagram for thick sheets [PDF]

open access: yes, 2014
In this paper a combined procedure to determine the forming limit diagram (Keeler-Goodwin diagram) for thick sheets is proposed. It is defined for cold rolled steel sheet Č0147 (RSt 13 DIN 17006) with thickness of 5 mm using two different criteria ...

Determining Forming Limit Diagrams Using Sub-Sized Specimen Geometry and Comparing FLD Evaluation Methods

open access: yesMetals, 2021
Sheet metal forming boundaries are established using the forming limit diagram (FLD). The Nakajima and Marciniak tests, which are based on stretching a material using a punch, are the most commonly used methods for determining the FLD or fracture forming
