Molecular rotor dynamics influenced by the elastic modulus of polyethylene nanocomposites [PDF]

The Journal of Chemical Physics, 2009
We observed that the excited-state twisting motion of 3,3′-diethyloxacarbocyanine in polymer nanocomposites (PNCs) depends strongly on the elastic modulus of medium. PNCs consist of low density polyethylene dispersed with surface-functionalized nanodiamonds with various alkyl groups.

Prediction of porosity of pervious concrete based on its dynamic elastic modulus

Results in Materials, 2021
In this research, we put forward a simple physical model of pervious concrete (PC) consisting of pore, aggregate and cement paste to evaluate theoretically the elastic modulus–porosity relationship.

A New Correlation for Estimating Static Elastic Properties of Sandstone Formations: Case Study from Rumaila Oilfield

Iraqi Geological Journal
Evaluating the elastic characteristics of reservoir's rocks is crucial for the oil and gas sector to reduce risks throughout drilling and production operations. Elastic parameters are essential for prediction of wellbore stability, estimation of

Undrained Dynamic Behavior of Reinforced Subgrade under Long-Term Cyclic Loading

Advances in Materials Science and Engineering, 2018
To study the dynamic behavior of reinforced subgrade, a series of undrained cyclic triaxial tests of reinforced soil (the specimen a height of 50 cm and a diameter of 20 cm) were performed in this paper.

Estimation of the static modulus of elasticity of wood from the dynamic modulus of elasticity

Forest Systems
Aim of study: Analyze the behavior and predictive capacity of different non-destructive testing (NDT) methods—ultrasound, longitudinal and transverse vibrations, and static bending— for estimating the MOEGTO in two species of great forestry interest in Europe: Pinus sylvestris and Populus × euramericana.

Eccentric Exercise Reduces Upper Trapezius Muscle Stiffness Assessed by Shear Wave Elastography and Myotonometry

Frontiers in Bioengineering and Biotechnology, 2020
In this study, we tested the hypotheses that unaccustomed eccentric exercise (ECC) would reduce the elastic modulus and dynamic stiffness of the upper trapezius muscle and that these changes would correlate with increases in muscle thickness, reflecting ...

Effect of nano-SiO2 and nano-CaCO3 on the static and dynamic properties of concrete

Scientific Reports, 2022
Three kinds of nano-concrete, i.e., 2.0% nano-SiO2 doped, 2.0% nano-CaCO3 doped and 1.0% nano-SiO2-1.0% nano-CaCO3 co-doped concretes (NS, NC, NSC) were prepared for a study on static property and dynamic property under different strain rates (50–130 s−1)

On the Lightweight Potential of Laser Additive Manufactured NiTi Triply Periodic Minimal Sheet Lattices

Advanced Engineering Materials, EarlyView.
This study explores the lightweight potential of laser additive‐manufactured NiTi triply periodic minimal surface sheet lattices. It systematically investigates the effects of relative density and unit cell size on surface quality, deformation recovery, compression behavior, and energy absorption.
