Quantitative analysis of deformation in hollow cylinder tests on anisotropic clay formations

Vincent Labiouse, Shuang You

A series of triaxial laboratory experiments are performed on thick-walled hollow cylindrical samples of boom clay. The aim of this testing program is to better understand the anisotropic deformation during the excavation. The testing conditions are similar ...

A deep crust-mantle boundary in the asteroid 4 Vesta

Philippe Gillet, Harold Gabriel Eugène Justin Clenet

The asteroid 4 Vesta was recently found to have two large impact craters near its south pole, exposing subsurface material. Modelling suggested that surface material in the northern hemisphere of Vesta came from a depth of about 20 kilometres, whereas the ...

Punching resistance and flexural behaviour of continuous flat slabs

Aurelio Muttoni, Miguel Fernández Ruiz, Jürgen Einpaul

The punching resistance of actual reinforced concrete flat slabs is potentially influenced by the compressive membrane action, which may significantly increase their resistance compared to isolated laboratory specimens. However, design codes have been deve ...

Impact of internal crystalline boundaries on lattice thermal conductivity: Importance of boundary structure and spacing

Jean-François Molinari, Guillaume Anciaux, Ramin Aghababaei

The low thermal conductivity of nano-crystalline materials is commonly explained via diffusive scattering of phonons by internal boundaries. In this study, we have quantitatively studied phononcrystalline boundaries scattering and its effect on the overall ...

Snakes with Tangent-Based Control and Energies for Bioimage Analysis

Michaël Unser, Ricard Delgado Gonzalo, Virginie Sophie Uhlmann

We propose a novel active contour for the analysis of filament-like structures and boundaries—features that traditional snakes based on closed curves have difficulties to delineate. Our method relies on a parametric representation of an open curve involvin ...

The structure and effect of suture zones in the Larsen C Ice Shelf, Antarctica

Konrad Steffen

Ice shelf fractures frequently terminate where they encounter suture zones, regions of material heterogeneity that form between meteoric inflows in ice shelves. This heterogeneity can consist of marine ice, meteoric ice with modified rheological properties ...
