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.

The study on the fatigue FEM analysis considering the effect of stamping
TL;DR: In this article, a database modification approach was proposed to integrate the stamping effects into the fatigue FEM prediction for an engine bracket in an accelerated rig test, which increased the predicted fatigue life greatly and also improved the accuracy of the fatigue prediction.

Residual stress state at different scales in deep drawn cup of unstable austenitic steel
TL;DR: In this article, residual stresses state at different scales in the 301LN unstable austenitic steel after deep drawing was determined. But the authors focused on the characterization of the martensitic transformation during uniaxial loading.

Some Applications of the Barlat 1991 Yield Criterion
TL;DR: In this paper, it is shown that a yield criterion proposed by Barlat et al. (1991) gives good results and preserves simple operational use, based on the generally accepted framework of a yield surface and associative flow.
Plasticity effects in subsequent simulations of car structures
