Current-sheet formation near a hyperbolic magnetic neutral line in the presence of a plasma flow with a uniform shear-strain rate: An exact solution

open access: greenPhysics Letters A, 1999
Abstract An exact solution for the magnetohydrodynamic (MHD) equations for a time-dependent, two-dimensional flow of an incompressible plasma with a uniform shear-strain rate in hyperbolic magnetic field is given. This solution predicts that the presence of a shear-strain in the plasma-flow tends to impede the current-sheet formation near the ...

Modeling seismic compression of unsaturated soils in the funicular regime [PDF]

open access: yesE3S Web of Conferences, 2023
A semi-empirical elasto-plastic constitutive model with a hyperbolic stress-strain curve was developed with the goal of predicting the seismic compression of unsaturated sands in the funicular regime of the soil-water retention curve (SWRC) during ...

Study on the cohesive shear characteristics and intrinsic modelling of the root–tailing soil interface of Amorpha fruticosa

open access: yesScientific Reports, 2022
To study the soil consolidation effect of shrub plant roots on tailings soil and to explore the frictional characteristics of plant roots on tailings soil, three experimental conditions of the root–soil interface were established by using a modified ...

Creep tests and creep model for reconstituted over-consolidated saturated clay

open access: yesYantu gongcheng xuebao, 2023
The triaxial shear creep tests are carried out on the reconstituted over-consolidated clay samples (OCR=1.00, 1.25, 1.67, 2.00, 3.00) from Hangzhou, China. The time-dependent deformation characteristics and creep model for the over-consolidated saturated

Calculation of slip surface displacement in earth slopes using the limit equilibrium method [PDF]

open access: yesNumerical Methods in Civil Engineering, 2018
In the present study, shear displacements were calculated for all failure surface slices in earth slopes using the limit equilibrium method. To this end, the hyperbolic shear stress-strain constitutive law was applied.

Investigation of the Mechanical Behavior of Polypropylene Fiber-Reinforced Red Clay

open access: yesApplied Sciences, 2021
Red clay is not easy to use as a natural foundation because of its high water content, high plasticity index, large void ratio, and susceptibility to shrinkage and cracking.

Bending and Free Vibration Analysis of Functionally Graded Plates via Optimized Non-polynomial Higher Order Theories [PDF]

open access: yesJournal of Applied and Computational Mechanics, 2019
Optimization concept in the context of shear deformation theories was born for the development of accurate models to study the bending problem of structures. The present study seeks to extend such an approach to the dynamic analysis of plates.

Deflection of a hyperbolic shear deformable microbeam under a concentrated load [PDF]

open access: yesJournal of Applied and Computational Mechanics, 2016
Deflection analysis of a simply supported microbeam subjected to a concentrated load at the middle is investigated on the basis of a shear deformable beam theory and non-classical theory.

Dynamic Properties of Calcareous Sands from Urban Areas of Abu Dhabi

open access: yesApplied Sciences, 2022
Abu Dhabi (ABD) has recently developed its national building code that mandates dynamic analysis of large structures to seismic loadings. Large strain dynamic properties such as shear modulus (G) and damping ratio (D) of local undisturbed calcareous ...

Contour Measurement of Object with Arbitrary Surface Using Two-Dimensional Shearography with Source Displacement

open access: yesOptics, 2022
A two-dimensional (2D) shearography with source displacement is proposed to measure object contours. Using a dual-shear shearographic setup with two movable laser sources, the full-field slopes along a pair of orthogonal shear directions were obtained ...
