Effects of grain size distribution on the initial strain shear modulus of calcareous sand [PDF]

open access: yes, 2015
The soil’s small strain shear modulus, Gmax or G0, is applied in dynamic behavior analyses and is correlated to other soil properties (density and void ratio) for predicting soil dynamic behavior under seismic loadings such as earthquakes, machinery or ...

EBSD Study of Creep‐Induced Lattice Misorientation in MgO‐Particle‐Reinforced Austenitic Steel Composites

open access: yesAdvanced Engineering Materials, EarlyView.
Creep experiments at 900°C on coarse‐grained steel‐ceramic composites containing recycled magnesia reveal that higher ceramic volume fractions significantly enhance the creep resistance. Detailed EBSD investigations identify subgrain formation in the steel matrix as the dominant deformation mechanism.

Acoustic scattering from a strained region [PDF]

open access: yes, 2006
A composite material consists of a rubber filled with gas-filled microspheres. In underwater applications it is compressed hydrostatically by a pressure that may be not insignificant compared with the shear modulus of the rubber, so large strains are ...

Dynamic Modulus of Hard Polyurethane Foams.

open access: yesKOBUNSHI RONBUNSHU, 2000
本研究においては, 硬質ポリウレタンフォームの粘弾性測定器により測定した引張モード, 圧縮モードの動的弾性率, 損失正接について, 密度, 強度との比較, 気泡破壊前後の比較, 温度特性に関する検討, さらにフォームの簡単なモデルを設定して, 弾性率を推定した. その結果, 動的弾性率とかさ密度, 強度との関係において, 正の相関関係がみられた. 特に, 動的引張弾性率はかさ密度, 強度と良好な相関関係があった. 気泡破壊後の動的圧縮弾性率は気泡破壊前と比較してかなり小さくなった. 気泡の内圧と素材の弾性率がスケルトンの変形に対する抵抗に大きく影響を及ぼすと考えられる.

Piezoresistive Monitoring of Carbon Nanomaterial‐Reinforced Epoxy Composites Under Cyclic and Fatigue Loading: A Review

open access: yesAdvanced Engineering Materials, EarlyView.
Carbon nanomaterial‐reinforced epoxy composites exhibit pronounced piezoresistive behavior, enabling intrinsic damage sensing under cyclic and fatigue loading. This review critically compares carbon nanotube and graphene systems, correlating filler content, percolation threshold, and gauge factor with sensing stability and damage evolution.

Study on dynamic and static elastic moduli of shale oil by different loading methods

open access: yesUnconventional Resources, 2023
Experiments on the dynamic and static elastic parameters under distinct loading conditions help clarify the effects of loading rate and strain amplitude on dynamic and static elastic moduli, and gain further insight into the moduli.

Electrical Conductivities of Conductors, Semiconductors, and Their Mixtures at Elevated Temperatures

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents a comprehensive review of temperature‐dependent electrical conductivity data for multiple material classes at elevated temperatures, highlighting a persistent conductivity gap between metals and semiconductors in the range of 102$\left(10\right)^{2}$– 107$\left(10\right)^{7}$ S/m. Metal–ceramic irregular metamaterials are proposed

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

open access: yes, 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.
