Strong particles in Metal

Andreas Mortensen, Marco Cantoni, Goran Zagar, Raphaël Charvet, Cyril Dénéréaz, Martin Guillermo Mueller, Václav Pejchal, Marta Fornabaio, Lionel Michelet, Willy Dufour

We all know that strong fibers make most of today¹s composite materials what they are : exceptionally stiff, strong, light and tough materials that serve in a number of demanding structural applications. This presentation will try to make the case for stro ...

Modelling of the in-plane behaviour of masonry walls strengthened with polymeric grids embedded in cementitious mortar layers

Angelo Garofano

The seismic reinforcement of masonry walls needs to be carried out through appropriate and effective techniques aiming at providing both adequate strength and displacement capacity. The present research concerns experimental results about the in-plane beha ...

Temperature effects on material properties and structural response of polymer matrix composites

Wei Sun

Structural components used in civil engineering applications are often subjected to compressive loads. Unlike the tensile strength of fiber-reinforced polymer (FRP) materials, their compressive strength is resin-dominated, exhibiting lower values and more ...

EPFL2015

The accumulative roll bonding process is one of the most prominent severe plastic deformation processes for obtaining sheet materials with ultra-fine-grained microstructures and high strength. The properties of such sheets differ significantly from those o ...

Design of Self-Healing Supramolecular Rubbers with a Tunable Number of Chemical Cross-Links

Véronique Michaud, Federica Sordo

Supramolecular rubbers incorporating a large number of physical cross-links through cooperative hydrogen bonds display high self-healing properties but limited solvent and creep resistance due to the lack of chemical cross-links. Increasing both chemical c ...

Amer Chemical Soc2015

Combining biological components, such as cells and tissues, with soft robotics can enable the fabrication of biological machines with the ability to sense, process signals, and produce force. An intuitive demonstration of a biological machine is one that c ...

Exploring the Physics behind Dynamic Fragmentation through Parallel Simulations

Sarah Levy

The physical mechanisms underlying the dynamic fragmentation of heterogeneous brittle materials are explored through numerical simulations. The use of computational facilities, rather than experimental or fundamental sciences, ensures the accurate tracking ...

Model for fretting wear of brittle ceramics

Abhishek Tewari

In selecting and designing materials for certain engineering applications, the resistance to material damage or removal of material from contacting surfaces in relative motion is an important factor. To determine these properties, laboratory tests are rout ...

Hybrid microfluidic cartridge formed by irreversible bonding of SU-8 and PDMS for multi-layer flow applications

Nico de Rooij, Peter Van der Wal, Olivier Frey, Sara Talaei

SU-8 and polydimethylsiloxane (PDMS) are both transparent materials with properties very convenient for rapid prototyping of microfluidic systems. However, previous efforts of combining these two materials failed due to poor adhesion between them. Herein, ...
