Velocity Slip and Temperature Jump in Hypersonic Aerothermodynamics [PDF]
Hypersonic vehicles experience different flow regimes during flight due to changes in atmospheric density. Computational fluid dynamics, although relatively computationally inexpensive, is not physically accurate in areas of highly nonequilibrium flows.

This plot compares experimental tensile stress–strain curves (with 4 different strain rates) and corresponding modelled curves (obtained using the optimised sets of Voce and Miller–Norton parameter values shown). The inferred M‐N values, characterizing the creep, are very similar to those obtained via conventional creep testing.

A model for frictional sliding instability on a heterogeneous fault
An instability of frictional sliding driven by tectonic stress is assumed to be the source of earthquakes. Empirical slip laws indicate that, under constant ambient conditions, friction depends on time, slip rate and slip history.

Dynamic Model and Quantitative Analysis of Stick-Slip Vibration in Horizontal Well
Stick-slip is very harmful to the service life of drillstring. The extended Hamilton principle is applied in the paper. Then, finite element method (FEM) is employed to describe the model.

Incompressible Limit of isentropic Navier-Stokes equations with Navier-slip boundary
This paper concerns the low Mach number limit of weak solutions to the compressible Navier-Stokes equations for isentropic fluids in a bounded domain with a Navier-slip boundary condition.

Subducting slab ultra-slow velocity layer coincident with silent earthquakes in southern Mexico [PDF]
Great earthquakes have repeatedly occurred on the plate interface in a few shallow-dipping subduction zones where the subducting and overriding plates are strongly locked.

Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.

Blasius Problem with Generalized Surface Slip Velocity
This paper considers the classical problem of the steady boundary layer flow past a semi-infinite flat plate first considered by Blasius in 1908 with generalized surface slip velocity. Numerical solutions are obtained by solving the nonlinear similarity equation using the bvp4c function from MATLAB for several values of the slip parameters.

This study uncovers the unexplored role of intermolecular interactions in multiphoton absorption in coordination polymers. By analyzing [Zn2tpda(DMA)2(DMF)0.3], it shows how the electronic coupling of the chromophores and confinement in the MOF enhance two‐and three‐photon absorption.

FEEDBACK BOUNDARY OF 4:1 ROUNDED CONTRACTION SLIP FLOW FOR OLDROYD-B FLUID BY FINITE ELEMENT [PDF]
The driven force feedback in viscoelastic flow is a technique to enforce converged solution of Oldroyd-B fluid on the basis of semi-implicit TaylorGalerkin finite element method for 4:1 contraction geometry with rounded corner meshes.
