Piezoelectric Ring Bender for Characterization of Shear Waves in Compacted Sandy Soils
Sensors, 2021 Shear wave velocity and small-strain shear modulus are widely used as the mechanical properties of soil. The objective of this study is to develop a new shear wave monitoring system using a pair of piezoelectric ring benders (RBs) and to evaluate the ...

Using shear modulus to predict the bearing capacity of strip foundations on sand [PDF]
E3S Web of ConferencesThis paper reports results of a study to predict load-settlement behaviour of strip foundations on a dry uncemented sand using only soil stiffness data, under both working loads and extreme loads.

Preliminary findings on the experimental investigation of the small-strain behaviour of Pizzoli silty sand [PDF]
E3S Web of ConferencesThe dynamic properties of soils play a crucial role in solving many geotechnical problems with special attention to earthquake engineering. In particular, the small-strain soil behavior should be accurately reproduced in geotechnical modelling to allow ...

Contact Changes near Jamming [PDF]
, 2014 We probe the onset and effect of contact changes in soft harmonic particle packings which are sheared quasistatically. We find that the first contact changes are the creation or breaking of contacts on a single particle.

Macroscopic model with anisotropy based on micro-macro informations [PDF]
, 2014 Physical experiments can characterize the elastic response of granular materials in terms of macroscopic state-variables, namely volume (packing) fraction and stress, while the microstructure is not accessible and thus neglected.

Strain amplitude response and the microstructure of PA/clay nanocomposites [PDF]
, 2005 Polyamide 6/clay nanocomposites (PAn, where n is the mass fraction of clay) with various clay loading were prepared by melt compounding in a twin screw extruder. Exfoliation of clay in a PA matrix was confirmed by X-ray diffraction.

Dynamic Nonlinear and Residual Deformation Behaviors of the Fly Ash-Modified Loess
Shock and Vibration, 2021 Metastable loess soils can deform, inducing geological and engineering disasters. Therefore, the behavior of the loess under dynamic load is gaining massive attention from researchers to improve the strength of the soils.

Self-organization of adatom adsorption structure at interaction with tip of dynamic force microscope [PDF]
, 2014 The formation of an adatom adsorption structure in dynamic force microscopy experiment is shown as a result of the spontaneous appearance of shear strain caused by external supercritical heating.
