Comparison of Rheological Methods to Measure Grease Degradation
In a previous paper, methods that have been used to quantify grease mechanical degradation were compared, finding that crossover stress is a practical method for estimating the cone penetration value of a grease using a small sample.

The influences of partial saturation on cone penetration tests in silty gold tailings [PDF]
Laboratory-controlled cone penetration test results of a silty gold tailings in a variety of saturated and unsaturated states, obtained using two calibration chambers, are presented then interpreted using a state parameter-based approach.

Mechanical performance analysis of hollow cylindrical roller bearing of cone bit by FEM
Bearings are key components of cone bit, thus its rapid failure is a major cause of leading to lower life of the bit. To improve the bearing performance and prolong working life, contact mechanics of hollow cylindrical roller bearing of cone bit was ...

Universal hydrodynamic flow in holographic planar shock collisions [PDF]
We study the collision of planar shock waves in AdS$_5$ as a function of shock profile. In the dual field theory the shock waves describe planar sheets of energy whose collision results in the formation of a plasma which behaves hydrodynamically at late ...

Exact finite volume expectation values of $\bar{\Psi} \Psi$ in the Massive Thirring model from light-cone lattice correlators [PDF]
In this paper, using the light-cone lattice regularization, we compute the finite volume expectation values of the composite operator $\bar{\Psi}\Psi$ between pure fermion states in the Massive Thirring Model.

RESTRICTIONS ON STRESS COMPONENTS IN THE TOP OF ROUND CONE [PDF]
Summary: The stress state at a vertex of homogeneous or composite cone is studied using the concept of the point of deformed body considered as an elementary volume contractible to this point. Elementary volume represents an assembly of continuum points with a linear characteristic dimension equal to that of representative volume element of the ...

New shapes of light-cone distributions of the transversely polarized \rho-mesons [PDF]
We re-analyze the leading twist light-cone distributions for transversely polarized \rho-, \rho'- and b_1-mesons in the framework of QCD sum rules with nonlocal condensates.

Light-cone commutators of stress-tensor components
Abstract The commutator [ θ μν ( x ), θ ϱσ (0)] among components of the in the limit x 2 → 0. The related Bjorken limit of virtual graviton scattering is studied with special attention to its positivity restrictions and the ensuing conditions on the commutator.

X-ray residual stress measurements on cold-drawn steel wire [PDF]
The interplanar spacing d{hkl} versus sin2 ψ distributions were measured for the 211, 310, 220 and 200 reflections from severely cold-drawn 0.7% C steel wire with a diameter of 0.25 mm. From the shape of the curves it was concluded that, as well as a 110
