General Constitutive Relations of Anorthotropic 6061-T6 Aluminum and Its Fatigue Life under Proportional and Non-Proportional Loadings
H Nayeb-Hashemi,H Lin +1 more
TL;DR: Anisotropic constitutive relations with respect to the principal axes of an orthotropic solid are formulated using the macroscopic continuum plasticity theory of Shih and Lee as discussed by the authors, and the constitutive equations are used to predict the low-cycle fatigue life of this material under both proportional and non-proportional loadings.

Low-cycle fatigue of metal of rolled sheets with initial anisotropy of mechanical properties
TL;DR: In this article, the authors examined the relationship between low-cycle deformation and failure of the metal of rolled sheets (03Kh16N9M2 steel) with initial anisotropy of the mechanical properties, and showed that the cyclic characteristics of this material depend on the direction in which the specimens are cut out.
