Fabric evolution and the related swelling behaviour of a sand/bentonite mixture upon hydro-chemo-mechanical loadings

Lyesse Laloui, Alessio Ferrari, Donatella Manca

This experimental study investigates the swelling behaviour of an 80/20 sand/bentonite mixture and the associated fabric evolution under different hydro-chemo-mechanical loadings. Free and confined swelling tests are performed on specimens compacted to dif ...

Influence of microstructural heterogeneity on the scaling between flow stress and relative density in microcellular Al-4.5 %Cu

Andreas Mortensen, Yves Conde

We explore the influence of the metal microstructure on the compressive flow stress of replicated microcellular 400-mu m pore size Al-4.5 wt%Cu solidified at two different solidification cooling rates, in the as-cast and T6 conditions. It is found that the ...

Elasto-Dynamic Behavior of a Two-Dimensional Square Lattice With Entrained Fluid II: Microstructural and Homogenized Models

Alessandro Spadoni, Vladimir Dorodnitsyn

This paper presents a detailed study of the pressure waves and effective mechanical properties of a closed-cell cellular solid with entrained fluid. Plane-harmonic-waves are analyzed in a periodic square with a finite-element model of a representative-volu ...

Observations of continental biogenic impacts on marine aerosol and clouds off the coast of California

Athanasios Nenes, Zheng Wang

During the 2011 Eastern Pacific Emitted Aerosol Cloud Experiment (E-PEACE) and 2013 Nucleation in California Experiment (NiCE) field campaigns, a predominantly organic aerosol (> 85% by mass) was observed in the free troposphere over marine stratocumulus o ...

The formation and evolution of oxide particles in oxide-dispersion-strengthened ferritic steels during processing

Nadine Baluc

The fabrication of oxide-dispersion-strengthened (ODS) steels is a multi-stage process involving powder ball milling, degassing and consolidation by hot isostatic pressing. Y is introduced by mechanical alloying (MA) with either Y2O3 or Fe2Y so a high dens ...

Looking for differences in wood properties as a function of the felling date: lunar phase-correlated variations in the drying behavior of Norway Spruce (Picea abies Karst.) and Sweet Chestnut (Castanea sativa Mill.)

Rodolphe Schlaepfer

A large-scale field experiment on the drying behavior of Norway Spruce (Picea abies Karst.) and Sweet Chestnut (Castanea sativa Mill.) in relation to the felling date was conducted over a period of 24 weeks in order to investigate the existence of variatio ...

Mass density of individual cobalt nanowires

Dongfeng Zhang

The mass density of nanowires is determined using in situ resonance frequency experiments combined with quasi-static nanotensile tests. Our results reveal an average mass density of 7.36 g/cm3, which is below the theoretical density of bulk cobalt. The res ...
