Preliminary findings on the experimental investigation of the small-strain behaviour of Pizzoli silty sand [PDF]

E3S Web of Conferences
The 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 ...

In situ shear wave velocity from multichannel analysis of surface waves (MASW) tests at eight Norwegian research sites

, 2007
The Multichannel Analysis of Surface Waves (MASW) technique, used to determine shear wave velocity (Vs) and hence small strain stiffness (Gmax), has recently generated considerable interest in the geophysics community.

A Critical Review of Cone Penetration Test-Based Correlations for Estimating Small-Strain Shear Modulus in North Sea Soils

Geotechnics
The geotechnical characterisation of offshore wind farm sites requires measurement or estimation of the small-strain shear stiffness Gmax of the subsoil.

A Numerical–Experimental Approach for Multi‐Matrix Fiber‐Reinforced Plastics Characterization Using Finite Element Model Updating

Advanced Engineering Materials, EarlyView.
A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Prediction models and associated uncertainty for dynamic shear modulus and damping ratio of Beijing silty clay

Scientific Reports
Based on experimental data of normalized shear modulus and damping ratio from undisturbed silty clay within 120 m depth in the Beijing area, the Davidenkov backbone curve is used to characterize the normalized shear modulus curve, and the damping ratio ...

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.

Additive Gaussian Process Regression for Predictive Design of High‐Performance, Printable Silicones

Advanced Engineering Materials, EarlyView.
A chemistry‐aware design framework for tuning printable polydimethylsiloxane (PDMS) for vat photopolymerization (VPP) is developed using additive Gaussian process (GP) modeling. Polymer network mechanics informs variable groupings, feasible formulation constraints, and interaction variables.

Discussions on elastic parameters of soil for land subsidence caused by decompression of confined aquifer in deep excavation

Yantu gongcheng xuebao, 2017
The relationships among the soil shear modulusobtained by oedometer tests, by pumping tests and the initial shear modulusof hardening soil small (HSS) model for soft soil under sensitive circumstance in Shanghai and Tianjin are studied. The HSS model is

Experimental study of effect of wetting-drying path on small-strain shear modulus of silt

, 2015
Natural soils are usually under unsaturated state, especially soils at shallow depths below ground. The small-strain shear modulus of unsaturated soil is an important parameter for predicting ground deformation and dynamic responses of earth structures ...

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated
