Ball-burnishing effect on deep residual stress on AISI 1038 and AA2017-T4
A. A. Garcia-Granada,Giovanni Gómez-Gras,Ramón Jerez-Mesa,J. Antonio Travieso-Rodriguez,Guillermo Reyes +4 more
TL;DR: In this article, the incremental hole drilling (IHD) technique is tested to measure residual stresses, being able to reach a 2-mm measuring depth, and a commercial strain gage is used and calibrated using finite element model simulations.

Determination of Anisotropic Yield Coefficients by a Data-Driven Multiobjective Evolutionary and Genetic Algorithm
TL;DR: In this article, a robust multiobjective optimization based on evolutionary algorithm is proposed to minimize the error in yield stress and plastic strain ratio simultaneously and thereby overcomes the limitations in the approaches used before.

Lin Wang,Tai Chiu Lee +1 more
TL;DR: In this article, the authors proposed Forming Limit Curve (FLC) which is used to evaluate the necking risk, differs a lot while different yield criteria used, such as Hill 48, Hill 90 and Hill 93.

Effect of ironing on the residual stresses in deep drawn cups
M.S. Ragab,H.Z. Orban +1 more
TL;DR: In this article, the effect of ironing on the magnitude and distribution of the bending residual stresses in deep drawn cups was investigated and it was found that the residual stresses after deep drawing can be reduced greatly by ironing the cups with relatively small ironing strains.

A plane stress anisotropic plastic flow theory for orthotropic sheet metals
TL;DR: In this paper, a phenomenological theory is presented for describing the anisotropic plastic flow of orthotropic polycrystalline aluminum sheet metals under plane stress, which uses a stress exponent, a rate-dependent effective flow strength function, and five material functions to specify a flow potential, an associated flow rules of plastic strain rates, a flow rule of plastic spin and an evolution law of isotropic hardening of a sheet metal.

Occurence of strain path changes in a two-stage deep drawing process
TL;DR: In this article, the influence of the strain path change on the prediction of the deep drawing of cylindrical cups was analyzed using the Hill's 1948 yield criterion associated with three different hardening laws: a purely isotropic hardening, a mixed hardening with both isotropics and nonlinear kinematic contributions and a dislocation-based hardening model, which takes into account transient behaviors recorded during strain path changes.

Effect of prestrain paths on mechanical behavior of dual phase sheet steel
TL;DR: In this article, the tensile and fatigue performance of dual phase (DP600) sheet steel was investigated with specimens, as-received, and with two different prestrain path conditions, uniaxial and plane strain.
