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.

A theory of the yielding and plastic flow of anisotropic metals
TL;DR: In this article, a theory is suggested which describes the yielding and plastic flow of an anisotropic metal on a macroscopic scale and associated relations are then found between the stress and strain-increment tensors.
Journal ArticleDOI
Limit strains in the processes of stretch-forming sheet metal
TL;DR: In this paper, a theoretical analysis of the process of the generation of the groove based on anisotropic plasticity theory is presented, and the system of equations derived was solved numerically with the aid of a computer, which enabled the limiting strain of the sheet metal to be determined as a function of the material.

Frédéric Barlat,Frédéric Barlat,J.C. Brem,Jeong W. Yoon,Jeong W. Yoon,Kwansoo Chung,Re Dick,D.J. Lege,Farhang Pourboghrat,Shi-Hoon Choi,E. Chu +10 more
TL;DR: In this article, a plane stress yield function that well describes the anisotropic behavior of sheet metals, in particular, aluminum alloy sheets, was proposed, which was introduced in the formulation using two linear transformations on the Cauchy stress tensor.

Residual stress. Part 1 – Measurement techniques
TL;DR: In this paper, the effect of residual stresses on fatigue lifetimes and structural integrity are first summarised, followed by the definition and measurement of residual stress, which are characterised according to the characteristic length scale over which they self-equilibrate.
