Abstract

The study is about the determination of the fatigue life curves for strain-controlled torsional loads on the basis of 6082-T6 aluminium alloy experimental data. ‘Diabolo’ type full specimens have been tested on newly designed test stand. Tree models and two fitting methods were used to determine strain-life curve constraints. The models used in this paper were: Kandil, Langer and recently proposed Kurek-Łagoda. And the methods were standard least squares approach and bisquare waged approach. MATLAB software was used for curve fitting for this article.
