TLDR
In this article, the residual stresses of sheet metal deformation during forming induces complex residual stresses in the component owing to its geometry and material anisotropy, which affect the durability of the component.Abstract:

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.
Journal ArticleDOI
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.

Anisotropy effects on the fatigue behaviour of rolled duplex stainless steels
TL;DR: In this article, the mechanical response of a 5 mm thick rolled plate of EN 1.4462 type duplex steel was characterised, with the transverse orientation exhibiting a mechanical response higher than that of the longitudinal one, considering the correlation between the crystallographic texture of each phase and their behaviour with respect to crack nucleation and early growth of short cracks.

Comparative study of precipitation behavior and texture formation in cold rolled-batch annealed and cold rolled-continuous annealed interstitial free high strength steels
TL;DR: In this paper, two interstitial free high strength (IFHS) steels of comparable chemistries but processed through batch and continuous annealing routes have been studied and the near absence of FeTiP and presence of a large volume fraction of TiC are considered to be primarily responsible for the sharp {1 1 1} texture in the CA steel.

Friction measurement apparatus for sheet metal forming
TL;DR: In this paper, two physical models or friction simulators based on the stretching of a strip around a pin were developed to characterize sheet metal forming friction, in contrast to other test apparatus which use measurements of strain to infer friction forces, these apparatus use direct measurements of forces.
Journal ArticleDOI
Evaluation of sheet metal formability, viscous pressure forming (VPF) dome test
TL;DR: In this paper, the authors used finite element-based code DEFORM to determine the formability of sheet metal in stretching using a critical damage value concept, which was found to be higher than that of the sheet stretched with a hemispherical solid metal punch.

Numerical modelling and simulation in sheet metal forming
TL;DR: In this article, the authors overview the present situation of numerical modelling and simulation in sheet metal forming, mainly from the viewpoint of scientific research and industrial applications, and explain the emerging role of modeling and simulation can also be explained by the growing globalisation and competition of the world market requiring shorter lead times and more cost effective solutions.
