Mechanical properties of tungsten alloys with Y2O3 and titanium additions [PDF]

open access: yes, 2011
In this research the mechanical behaviour of pure tungsten (W) and its alloys (2 wt.% Ti–0.47 wt.% Y2O3 and 4 wt.% Ti–0.5 wt.% Y2O3) is compared. These tungsten alloys, have been obtained by powder metallurgy.

Characterization of ripplocation mobility in graphite

open access: yesMaterials Research Letters, 2020
Recent work suggests that layered solids deform through buckling of basal planes. When isolated locally, as in graphite, these buckles, termed ripplocations, behave superficially similar to dislocations, but have no Burgers vectors.

Micro-mechanism analysis of shale gas migration

open access: yes工程科学学报, 2018
For shale gas exploitation, it is scientifically essential to clarify the mechanism of gas flow in nanopore media. Shale is a kind of tight rock, whose pore size mainly ranges from several nanometers to dozens of nanometers.

Singular inextensible limit in the vibrations of post-buckled rods: Analytical derivation and role of boundary conditions [PDF]

open access: yes, 2014
In-plane vibrations of an elastic rod clamped at both extremities are studied. The rod is modeled as an extensible planar Kirchhoff elastic rod under large displacements and rotations. Equilibrium configurations and vibrations around these configurations

Rheological Mechanism and Adhesion Properties of SBS Latex Modified Emulsified Asphalt

open access: yesTaiyuan Ligong Daxue xuebao
Purposes SBS modified emulsified asphalt has excellent performance, but it is difficult to emulsify SBS modified asphalt in its preparation process because of its high viscosity. Methods In this paper, SBS latex modified emulsified asphalt (SBS-LMEA) was

Effects of microstructure and crystallography on crack path and intrinsic resistance to shear-mode fatigue crack growth [PDF]

open access: yesFracture and Structural Integrity, 2015
The paper focuses on the effective resistance and the near-threshold growth mechanisms in the ferritic-pearlitic and the pure pearlitic steel. The influence of microstructure on the shear-mode fatigue crack growth is divided here into two factors: the ...
