Criticality in the Approach to Failure in Amorphous Solids

Failure of amorphous solids is fundamental to various phenomena, including landslides and earthquakes. Recent experiments indicate that highly plastic regions form elongated structures that are especially apparent near the maximal shear stress Sigma(max) w ...

Parameterization of bottom mixed layer and logarithmic layer heights in central Lake Erie

Damien Bouffard

The bottom boundary layer in lakes lies directly above the sediments and influences both hydrodynamic processes and biogeochemical fluxes. Several parameter-based models have been developed to predict the boundary layer characteristics, but the relative ac ...

Size effects in drift capacities of URM walls

Katrin Beyer, Sarah Petry

Examining the results of a large set of quasi-static cyclic tests on unreinforced masonry (URM) walls showed that the drift capacity of URM walls reduces with increasing wall size. Such a size effect is of concern since most wall tests were carried out on ...

Design and characterization of a soft magneto-rheological miniature shock absorber for a controllable variable stiffness sole

Yves Perriard, Yoan René Cyrille Civet, Daniel Grivon

The proposed paper discusses the design and characterization of a soft miniature Magneto-Rheological (MR) shock absorber. In particular, the final application considered for the insertion of the designed devices is a controllable variable stiffness sole fo ...

3D zero-thickness coupled interface finite element: Formulation and application

Anne-Catherine Adolphine M Dieudonné

In many fields of geotechnical engineering, the modelling of interfaces requires special numerical tools. This paper presents the formulation of a 3D fully coupled hydro-mechanical finite element of interface. The element belongs to the zero-thickness fami ...

On measuring fracture toughness under load control in the presence of slow crack growth

Andreas Mortensen, Goran Zagar, Martin Guillermo Mueller, Václav Pejchal, Aparna Singh

The influence of slow crack growth in ceramics on the measurement of their fracture toughness under steadily increasing controlled load (as is generally practiced in microscale testing) is analyzed to identify conditions under which the phenomenon can caus ...

Rinforzo di pannelli in muratura con griglie in materiali compositi immerse in matrici cementizie

Angelo Garofano

In the present paper the experimental results of in-plane shear tests on masonry walls subject to cyclic loads under constant axial load and externally strengthened with composite grid embedded in a cementitious matrix are synthetized. The experimental res ...

Interaction between in-plane shear forces and transverse bending moments in concrete bridge webs

Aurelio Muttoni, Miguel Fernández Ruiz, Marie-Rose Backes

This paper investigates a reliable design approach for reinforced concrete panels subjected to the combined action of in-plane shear and out-of-plane bending moments, which develop in webs of boxgirder bridges and similar structures. Neglecting this intera ...

Investigation of a new steel-concrete connection for composite bridges

Jean-Paul Lebet, Dimitrios Papastergiou

A new type of connection for steel-concrete composite bridges was developed by the Steel Structures Laboratory of Ecole Polytechnique Fédérale de Lausanne. Resistance to longitudinal shear is based on the development of shear stresses in the confined inter ...

Experimental investigation and modelling of the structural behaviour of confined grouted interfaces for a new steel–concrete connection

Jean-Paul Lebet, Dimitrios Papastergiou

Confined interfaces between cement grout and other materials such as embossed steel or rough concrete are formed in an innovative new steel-concrete connection for composite bridges. This article presents the experimental study of such interfaces and inves ...
