I consider the nonaxisymmetric linear theory of an isothermal magnetohydrodynamic (MHD) shear flow. The analysis is performed in the shearing box, a local model appropriate for a thin disk geometry. Linear perturbations in this model can be decomposed in terms of shearing waves (shwaves), which appear spatially as plane waves in a frame comoving with the shear. The time dependence of these wave...

In this paper, the in-plane torsional properties of two dimensional nanomaterials are revealed to be tunable by surface functionalization using molecular dynamics simulations. The torsional strengths of both graphene and graphyne under circular shearing are found to first decrease and then increase anomalously with the increase of the hydrogenation ratio. The minimum strength of such U-shaped s...

The surface morphology of joints directly determines the contact area and peak shear strength rock in shearing. This research gives a detailed description three-dimensional roughness parameters proposed by Grasselli, discusses characteristics parameter C different ranges. Quoting Xia's direct test data, relationship strength, strength/normal stress, residual dilation with normal stress are stud...

We present hydro-mechanical measurements that characterize shear on natural fractures in schist, amphibolite, and rhyolite specimens from the enhanced geothermal system (EGS) Collab Project's Experiment 1 2 sites (E1 E2) at Sanford Underground Research Facility. employed a triaxial direct method augmented with X-ray imaging to perform hydroshearing (injection-induced shearing) mechanical sheari...

In this paper, a Shearing Invariant Texture Descriptor (SITD) is proposed, which is a theoretically and computationally simple method based on the Rotation invariant Local Binary Pattern (Rot-LBP) descriptor. In real-world applications using flatbed scanners, such as paper texture fingerprinting, it’s common for a sheet of paper to rotate during the image acquisition process. Because the rotati...

The activation energies associated with the formation of a superlattice intrinsic stacking fault (SISF) from an antiphase domain boundary (APB) and the formation of a superlattice extrinsic stacking fault (SESF) from a complex stacking fault (CSF) in g 0 phase of Ni-based superalloys are calculated using a microscopic phase field dislocation model in combination with the nudged elastic band (NE...
