Variational phase-ﬁeld study of adhesive wear: elastic and elastic-plastic models

Wear is well known for causing material loss in a sliding interface. Available macroscopic approaches are bound to empirical ﬁtting parameters. We propose a study of the physical processes that lead to wear at the scale of the surface roughness, where adhe ...

Experimental investigation of strength, stiffness and drift capacity of rubble stone masonry walls

Katrin Beyer, Amir Rezaie, Michele Godio

There is limited available research on rubble stone masonry walls, which are vulnerable under seismic loading. This paper presents an experimental campaign of cyclic shear compression tests on six large-scale walls of this topology. The effect of the axial ...

Experimental investigations on the load-carrying capacity of digitally produced wood-wood connections

Yves Weinand, Julien Gamerro, Jean-François Bocquet

The rise of digital fabrication has increased the use of wood-wood connections inspired by traditional carpentry in modern timber constructions. With recent developments on standard construction systems, the mechanical behavior of such joints for in-plane ...

Effect of Ag Addition on the Hot Deformation, Constitutive Equations and Processing Maps of a Hot Extruded Mg-Gd-Y Alloy

Roland Logé

Hot deformation behavior of the extruded Mg-6Gd-3Y (GW63) and Mg-6Gd-3Y-1Ag (GW63-1Ag) alloys was assessed by shear punch testing (SPT) method in the temperature range of 623 K to 723 K and shear strain rate of 1.6 x 10(-2)to 1.3 x 10(-1) s(-1). Microstruc ...

Origin of the Temporal Evolution of Elastic Properties During Laboratory Seismic Cycle

Marie Estelle Solange Violay, François Xavier Thibault Passelègue, Mateo Alejandro Acosta, Federica Paglialunga

Recent seismological observations highlighted that earthquakes are associated to drops in elastic properties around the fault zone (Brenguier et al., 2008). This drop is often attributed to co-seismic damage produced at the rupture tip, and can mostly be o ...

H0LiCOW-XI. A weak lensing measurement of the external convergence in the field of the lensed quasar B1608+656 using HST and Subaru deep imaging

Frédéric Courbin, Georges Meylan, David Richard Harvey, Austin Chandler Peel, Vivien François Bonvin, Olga Tihhonova

We investigate the environment and line of sight (LoS) of the H0LiCOW (H-0 Lenses in COSMOGRAIL's Wellspring) lens B1608+656 using Subaru Suprime-Cam and the Hubble Space Telescope (HST) to perform a weak lensing analysis. We compare three different method ...

Euclid: Reconstruction of weak-lensing mass maps for non-Gaussianity studies

Georges Meylan, Yi Wang, Richard Massey

Weak lensing, which is the deflection of light by matter along the line of sight, has proven to be an efficient method for constraining models of structure formation and reveal the nature of dark energy. So far, most weak-lensing studies have focused on th ...

Numerical investigation of the role of masonry typology on shear strength

Katrin Beyer, Shenghan Zhang

The force-displacement behavior of masonry elements depends on the properties of their constituents, mortar and unit, as well as on their typology, i.e., the shape and size of the units and the patterns they generate. Up until now, only few numerical studi ...

Semi-Rigidity of Through-Tenon Joints under Tension and Shear Loads and Perpendicular-to-Grain Compression

Yves Weinand, Aryan Rezaei Rad, Anh Chi Nguyen

This report presents the results of experimental tests performed on through-tenon joints used in double-layered and double-curved timber plate shells recently developed. Three tests were carried out to determine the semi-rigidity of these wood-wood connect ...

Time-dependent strength of concrete in compression and shear

Darko Tasevski

Sustained load actions are permanently present in concrete structures, as for example self-weight and dead loads on bridges or soil pressure on cut-and-cover tunnels. These actions may increase throughout a structure's lifetime, for instance after refurbis ...
