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.

Plastic behavior and stretchability of sheet metals. Part I: A yield function for orthotropic sheets under plane stress conditions
Frédéric Barlat,K. Lian +1 more
TL;DR: In this article, a yield function that describes the behavior of orthortropic sheets, metals exhibiting planar anisotropy and subjected to plane stress conditions is proposed, which is shown to give a reasonable approximation to plastic potentials calculated with the Taylor/Bishop and Hill theory of polycrystalline plasticity for plane stress states.

A six-component yield function for anisotropic materials
TL;DR: In this paper, a new six-component yield surface description for orthotropic materials is developed, which has the advantage of being relatively simple mathematically and yet is consistent with yield surfaces computed with polycrystal plasticity models.
