This paper describes a fully implicit algorithm developed and optimized to simulate sheet
metal forming processes. This algorithm was implemented in the in-house code DD3IMP …

The Swift test was originally proposed as a formability test to reproduce the conditions
observed in deep drawing operations. This test consists on forming a cylindrical cup from a …

Deep drawing is an extensively used press working process since it eliminates expensive
machining and welding operations and enables the production of components at a very high …

The onset of wrinkling in sheet metals is first analysed as an elastic–plastic bifurcation for
thin and shallow shells with compound curvatures. Plastic yielding is described using a …

For years, coated metal sheets have been used in cookware manufacturing. This paper
focuses on employing experimental and numerical analyses to determine the quality and …

The aim of this paper is to demonstrate the capability of the tangent additive Mori-Tanaka
scheme to simulate complex processes like sheet metal forming. The strengths of such …

In this work, the limit strains under as-received and pre-strained conditions of an interstitial-
free steel sheet were investigated by mechanical tests and numerical modeling. An original …

Nos processos tecnológicos de conformação plástica, a geometria inicial do material é
modificada, através da aplicação de esforços externos que induzem deformação plástica no …

The effects of sheet thickness and frictional condition between the punch and sheet on
formability is predicted and compared with the experimental results of the Erichsen test as a …

This thesis focuses on the principles of springback for 6022-T4 aluminum sheets, using a
special draw-bend test with a range of sheet tensions and tool radii. To model the …
