Journal ArticleDOI
Bidimensional strain measurement using digital images
TL;DR: In this article, the displacement field is approximated by an iterative process attempting to optimize the correlation between two pictures, the first one before strain and the second one after strain.
Journal ArticleDOI
Multi-level modelling of mechanical anisotropy of commercial pure aluminium plate: crystal plasticity models, advanced yield functions and parameter identification
Kai Zhang,Bjørn Holmedal,Odd Sture Hopperstad,Stephane Dumoulin,Jerzy Gawad,Jerzy Gawad,Albert Van Bael,P. Van Houtte +7 more
TL;DR: In this paper, the mechanical anisotropy of an AA1050 aluminium plate was studied by the use of five crystal plasticity models and two advanced yield functions, and the results were compared with data from tensile tests at every 15° from the rolling direction (RD) to the transverse direction (TD) in the plate.
Journal ArticleDOI
Quantitative analysis of grain refinement in titanium during equal channel angular pressing
Yongjun Chen,Yanjun Li,John C. Walmsley,Stephane Dumoulin,S.S. Gireesh,S. Armada,Pål Christian Skaret,Hans Jørgen Roven +7 more
TL;DR: In this paper, a strain-driven grain subdivision of commercial pure titanium during 1-8 passes of equal channel angular pressing (ECAP) at 723 K was investigated quantitatively by electron backscattering diffraction.
Journal ArticleDOI
Microstructure evolution of commercial pure titanium during equal channel angular pressing
Yongjun Chen,Yanjun Li,John C. Walmsley,Stephane Dumoulin,Pål Christian Skaret,Hans Jørgen Roven +5 more
TL;DR: In this paper, the microstructure development of commercially pure titanium during 3 and 4 passes of equal channel angular pressing (ECAP) has been investigated in detail by optical microscopy and electron backscattered diffraction (EBSD).
Journal ArticleDOI
Finite element modeling of equal channel angular pressing: Effect of material properties, friction and die geometry
TL;DR: In this paper, the effects of friction, initial material properties and die geometry on equal channel angular pressing have been investigated and the results show a dependency of the strain mainly on die geometry, and slightly on friction.
