Experimental investigation and theoretical models on dynamic shear moduli and damping ratios for Yellow River sediment under different influence factors

open access: yes工程科学学报, 2023
The dynamic shear modulus and damping ratio are essential parameters for the site seismic response analysis of major projects. During highway construction along the Yellow River, the feasibility of using Yellow River sediment as a subgrade filler has ...

Hyperbolic boundary layer in the vicinity of the shear wave front in shells of revolution [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Математика. Механика. Информатика
Hyperbolic boundary layer equations in thin shells of revolution are constructed in small vicinities of the shear wave fronts (taking into account its geometry) at edge shock loading of the normal type.

High performance microfluidic rectifiers for viscoelastic fluid flow [PDF]

open access: yes, 2012
The flow of Newtonian and non-Newtonian fluids within microfluidic rectifiers with a hyperbolic shape was investigated to assess the effect of the bounding walls on the diodicity of the microfluidic device and achieve high flow anisotropy.

Mechanical Stability Investigation of Advanced Composite Plates Resting on Elastic Foundations Using a New Four-Unknown Refined Theory

open access: yesFracture and Structural Integrity, 2019
A refined and simple shear deformation theory for mechanical buckling of composite plate resting on two-parameter Pasternak’s foundations is developed. The displacement field is chosen based on assumptions that the in-plane and transverse displacements ...

Experimental Investigation on Particle Breakage Behavior of Marine Silica Sand under High-Stress Triaxial Shear

open access: yesJournal of Marine Science and Engineering, 2023
There is often obvious particle breakage for silica sand under high-stress, which will lead to the bearing capacity reduction and excessive settlement of the foundation.

LCS Tool : A Computational Platform for Lagrangian Coherent Structures [PDF]

open access: yes, 2014
We give an algorithmic introduction to Lagrangian coherent structures (LCSs) using a newly developed computational engine, LCS Tool. LCSs are most repelling, attracting and shearing material lines that form the centerpieces of observed tracer patterns in

A family of higher-order single layer plate models meeting $C^0_z$ -- requirements for arbitrary laminates [PDF]

open access: yes, 2019
In the framework of displacement-based equivalent single layer (ESL) plate theories for laminates, this paper presents a generic and automatic method to extend a basis higher-order shear deformation theory (polynomial, trigonometric, hyperbolic, ...) to ...

Experimental Study on the Shearing Behaviour on the Interface between Coarse Sand and Concrete under High Stress

open access: yesGeofluids, 2021
The shear behaviour on the interface between soil and structure is a research hot point. Based on the RMT-150B rock mechanics test system, a series of high-stress direct tests were performed on the coarse sand under the condition of different moisture ...
