In this study, fuzzy logic was implemented to formulate the fuzziness of layer boundaries for a two-layered clay soil. A field of two-layered clay with fuzzy boundaries between layers was generated, and then the bearing capacity of strip footing on this field was calculated by the assumption of plane-strain conditions. The Mohr-Coulomb failure criterion was used and bearing capacity calculation...

Weyl semimetals (WSMs) constitute a 3D phase with linearly dispersing Weyl excitations at low energy, which lead to unusual electrodynamic responses and open Fermi arcs on boundaries. We derive a simple criterion to identify and characterize WSMs in an interacting setting using the exact electronic Green's function at zero frequency, which defines a topological Bloch Hamiltonian. We apply this ...

A new species of Seticornuta from Brazil is described and illustrated, the first record of this genus for the Brazilian fauna. This new species was found in a study that aimed to enhance knowledge of the Brazilian fauna of Metopiinae, analysing samples from the hydrographic basin of Rio Mogi Guaçu. A diagnosis, along with distribution information for Seticornuta species are provided.

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...

Here, we investigate the ultrastructural origins of the strength of bone, which is critical for proper physiological function. A combination of dual nanoindentation, three-dimensional elastic-plastic finite element analysis using a Mohr-Coulomb cohesive-frictional strength criterion, and angle of repose measurements was employed. Our results suggest that nanogranular friction between mineral pa...

Shear deformations of Cu57Zr43 bulk metallic glass (BMG) model systems are performed using molecular dynamics simulation. The results suggest that both the hydrostatic stress and the stress normal to the shear plane should affect the shear response (modified Mohr–Coulomb yield criterion). We see shear localization and shear band nucleation in both a small system of 2000 atoms, and large systems...
