Journal ArticleDOI
Development of an in-plane biaxial test for forming limit curve (FLC) characterization of metallic sheets
TL;DR: In this article, a servo-hydraulic testing machine with four independent dynamic actuators is proposed for the characterization of sheet metal forming, and a rigorous procedure for the detection of numerical and experimental forming strains is also presented.
Journal ArticleDOI
Theoretical and numerical study of strain rate influence on AA5083 formability
TL;DR: In this article, two different approaches are introduced to construct FLDs (forming limit diagrams) of an aluminum alloy sheet and evaluate the effect of the rate sensitivity index on its formability.
Journal ArticleDOI
Off-line compensation of the tool path deviations on robotic machining: Application to incremental sheet forming
Jérémy Belchior,Mario Guillo,Eric Courteille,Patrick Maurine,Lionel Leotoing,Dominique Guines +5 more
TL;DR: In this article, a robust and systematic method is first proposed to derive the elastic model of their structure and an efficient FE simulation of the process is then used to predict accurately the forming forces.
Journal ArticleDOI
Calibration of anisotropic yield criterion with conventional tests or biaxial test
TL;DR: In this paper, the authors used the Besson yield criterion to model the plastic anisotropic behavior of an aluminum alloy series 5000, and the parameters of this yield model have been identified by two different methods: a classical one, considering several homogeneous conventional experiments and an exploratory one, with only one biaxial test.
Journal ArticleDOI
Nonlinear interaction of geometrical and material properties in sandwich beam instabilities
TL;DR: In this article, an analytical and numerical characterization of local and global sandwich beam instabilities in a perfect linear framework is presented. But the results of the analysis are limited to the case of a single core.
