A Multivariate Adaptive Regression Spline Approach for Prediction of Maximum Shear Modulus and Minimum Damping Ratio

Engineering Journal, 2012
This study uses multivariate adaptive regression spline (MARS) for determination of maximum shear modulus (G max ) and minimum damping ratio (ξ min ) of synthetic reinforced soil. MARS employs confining pressure (σ, psi), rubber (r, %) and sand (s, %) as input variables. The outputs of the MARS are G max and ξ min .

DMA2022 Dynamic resistance and energy absorption of sandwich beam with based on micro-topology optimization with maximum shear modulus

, 2022
Abstract Based on the mechanical characteristics of the core layer, which withstands the shear stress and deformation of a sandwich beam, a topology optimization framework based on the bi-directional evolutionary structural optimization method is proposed to optimize the core layer composed of a periodic base cell with extreme shear stiffness ...

Rheological Behavior of a Dispersion of Small Lipid Bilayer Vesicles [PDF]

, 1997
Rheological behavior of a dispersion of small nearly-unilamellar phospholipid bilayer vesicles has been investigated. We conducted steady-state shear experiments and linear viscoelastic experiments.

Anomaly of the Internal Friction in the Helium Crystals Grown in the Burst-like Growth Mode

, 2014
The internal friction in the crystals grown in two modes, namely, slow and anomalously fast (burst-like growth) modes, is measured in the temperature range 0.49-0.75K at a frequency of about 75kHz.

Non-linear Elastic Response in Solid Helium: critical velocity or strain

, 2010
Torsional oscillator experiments show evidence of mass decoupling in solid 4He. This decoupling is amplitude dependent, suggesting a critical velocity for supersolidity. We observe similar behavior in the elastic shear modulus.

Statistical Variations and New Correlation Models to Predict the Mechanical Behavior and Ultimate Shear Strength of Gypsum Rock

Open Engineering, 2018
In this study, over 1000 data from the several research studies was used to characterize and compare the density, strengths, modulus, flexural strength, porosity and the ultimate shear strengths of the calcium rocks.

Mechanical property characterization of Borsic/aluminum laminates at room and elevated temperatures [PDF]

Six Borsic/aluminum laminate orientations exposed to a braze temperature cycle were tested in tension, compression, and shear to determine tangent modulus, maximum stress and strain, and Poisson's ratio of the laminates at room and elevated temperatures.

Dynamic Shear Properties of Recycled Waste Steel Slag Used as a Geo-Backfill Material

Shock and Vibration, 2019
Waste steel slag is a recycled industrial solid waste and is sometimes used as backfills, but the dynamic shear properties of waste steel slag have not been researched at present.

Stress overshoot in a simple yield stress fluid: an extensive study combining rheology and velocimetry

, 2011
We report a large amount of experimental data on the stress overshoot phenomenon which takes place during start-up shear flows in a simple yield stress fluid, namely a carbopol microgel.
