Study on initial fatigue damage of magnesium alloy under torsion and bending
Nihon Kikai Gakkai ronbunshu, 2015 Torsion and bending fatigue tests of magnesium alloy AZ31were carried out to investigate the initial damage under high cycle fatigue. The crystallographic orientation of crystals in which slip lines were occurred was analyzed by using electron back ...

Development of a prediction system for CRSS ratio in polycrystalline metals
Nihon Kikai Gakkai ronbunshu, 2023 Critical resolved shear stress (CRSS) determines the ease of slip deformation of metals. In crystal structures with low symmetry, such as the HCP structure, non-equivalent slip systems exist.

Estimation Method of Relative Slip in Fretting Fatigue Contact by Digital Image Correlation
Metals, 2022 An experimental method that can quantify relative slip was developed using digital image correlation (DIC) in order to evaluate the sliding portion. The bridge-type test setup was designed to establish the fretting contact condition.

Stick-slip and Torsional Friction Factors in Inclined Wellbores [PDF]
MATEC Web of Conferences, 2018 Stick slip is usually considered a phenomenon of bit-rock interaction, but is also often observed in the field with the bit off bottom. In this paper we present a distributed model of a drill string with an along-string Coulomb stiction to investigate the effect of borehole inclination and borehole friction on the incidence of stick-slip. This model is
