MULTIAXIAL FATIGUE OF A RAILWAY WHEEL STEEL [PDF]
Journal of Engineering Science and Technology, 2015 Uniaxial and biaxial torsional fatigue specimens were extracted from a railway wheel steel. The fatigue tests were performed with the stress ratio of R= -1 by using uniaxial and biaxial torsional fatigue test specimens at room temperature in air.

Strain Engineering of Antimonene by a First-principles Study: Mechanical and Electronic Properties
, 2018 In this work, we investigate the mechanical and electronic properties of monolayer antimonene in its most stable beta-phase using first-principles calculations. The upper region of its valence band is found to solely consist of lone pair p-orbital states,

Deep Underground Science and Engineering, EarlyView.The rock failure mode is significantly influenced by the contributing factors, such as the joint inclination, the initial confining pressure, and the unloading point. We found six typical rock failure modes after a large number of numerical tests. Abstract Excavation unloading damages rock masses, with preferential failure along geological defects in ...
