From concrete waste to walls An investigation of reclamation and digital technologies for new load-bearing structures

Corentin Jean Dominique Fivet, Stefana Parascho, Maxence Grangeot

Our research explores opportunities in using unaltered concrete rubbles from demolition for the digital construction of structural walls. Through research by iterative making, we identify relevant upcycling processes and design strategies and explore new t ...

Exploiting Marginal Stability in Slow-Fast Quasilinear Dynamical Systems

Alessia Ferraro

The accurate investigation of many geophysical phenomena via direct numerical simulations is computationally not possible nowadays due to the huge range of spatial and temporal scales to be resolved. Therefore advances in this field rely on the development ...

Despite edge columns being instrumental components of flat slabs, most punching research has focused on internal connections. Several particularities of edge columns, such as load eccentricity and moment transfer, require additional experimental investigat ...

Stick-slip phenomena and Schallamach waves captured using reversible cohesive elements

Jean-François Molinari, Thibault Didier Roch, Evelyne Pélagie Ringoot

Reversibility is of paramount importance in the correct representation of surface peeling in various physical settings, ranging from motility in nature, to gripping devices in robotic applications, and even to sliding of tectonic plates. Modeling the detac ...

Magmatic dikes are a naturally occurring type of fluid-driven fractures (Rivalta et al. 2015) propagating in the lithosphere due to buoyant forces emerging from the density difference between the host material and the injected fluid (more precisely the dif ...

How does seismic anisotropy evolve as a function of mineralogical and textural changes across ductile shear zones? – an experimental and modelling approach

Henri Joseph François Gilles Leclère

Strain localization and the development of ductile shear zones in the middle and lower crust play major roles in lithosphere dynamics. Geophysical imaging of ductile shear zones is an issue for ore geology, for the understanding of the lithosphere rheology ...

Induced seismicity in geologic carbon storage

Lyesse Laloui, Victor Vilarrasa Riano

Geologic carbon storage, as well as other geo-energy applications, such as geothermal energy, seasonal natural gas storage and subsurface energy storage imply fluid injection and/or extraction that causes changes in rock stress field and may induce (micro) ...

Load-strengthening versus load-weakening faulting in gouge-bearing faults: insights from triaxial saw-cut experiments

Marie Estelle Solange Violay, Carolina Giorgetti, Iskander Louhichi

Brittle reactivation of pre-existing faults is theoretically constrained by their friction, the stress field orientation, and magnitude. Thus, following the Mohr-Coulomb failure criterion, the increase in tectonic shear stress leads to the reactivation of ...

Under-ice convection dynamics in a boreal lake

Alfred Johny Wüest, Damien Bouffard, Sébastien Lavanchy, Hugo Nicolás Ulloa Sánchez

We investigated radiatively driven under-ice convection in Lake Onego (Russia) during 3 consecutive late winters. In ice-covered lakes, where the temperature of water is below the temperature of maximum density, radiatively driven heating in the upper wate ...
