Journal ArticleDOI
Linear transfomation-based anisotropic yield functions
TL;DR: In this article, two convex formulations are proposed to describe the anisotropic behavior of metals and alloys for a full stress state (3D) in general terms, and the type of input data recommended for the description of plastic anisotropy in sheet samples is discussed.
Journal ArticleDOI
Modeling of shear ductile fracture considering a changeable cut-off value for stress triaxiality
TL;DR: In this article, a macroscopic fracture criterion is proposed based on micro-mechanism analysis of nucleation, growth and shear coalescence of voids from experimental observation of fracture surfaces.
Journal ArticleDOI
Prediction of six or eight ears in a drawn cup based on a new anisotropic yield function
TL;DR: Barlat et al. as mentioned in this paper proposed a linear transformation based anisotropic yield function, Yld2004-18p, for cup drawing simulation of a circular blank sheet, which is implemented in a finite element (FE) code.
Journal ArticleDOI
Plane stress yield function for aluminum alloy sheets—part II: FE formulation and its implementation
Jeong Whan Yoon,Jeong Whan Yoon,Frédéric Barlat,Frédéric Barlat,Robert E. Dick,Kwansoo Chung,Tae Jin Kang +6 more
TL;DR: Gelin et al. as discussed by the authors proposed a plane stress yield function based on Yld2000-2d for aluminum alloy sheets, which was implemented in a finite element code and compared with those of previously suggested yield functions.
