Dislocations 2016

Jean-François Molinari, Guillaume Anciaux, Jaehyun Cho

Dislocation dynamics are important to understand material plasticity in small-sized materials. In case of face-centered cubic crystalline systems, densities of initial dislocations, dislocation nucleations and starvations processes influence material stren ...

Capillarity in pressure infiltration: influence of percolation and wetting angle

Andreas Mortensen, William Craig Carter, Ludger Weber, Alain Léger, Gionata Schneider

Composite materials are often produced by pressure-infiltration of a liquid matrix into a preform of packed solid fibers or particles. Capillary forces that intervene in this process are quantified by measuring saturation curves, which are plots of the fra ...

Probing the local strength and toughness of microscopic hard second phases in metals and composites

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

Many engineering alloys and composites combine a ductile matrix with discrete microscopic reinforcing phases, e.g. silicon particles in aluminium alloys, carbides in steels or ceramic particles in metal matrix composites. It is well understood that the mec ...

The local strength of microscopic alumina reinforcements

Andreas Mortensen, Marco Cantoni, Goran Zagar, Andreas Rossoll, Martin Guillermo Mueller, Václav Pejchal

We measure, using an adaptation of a method designed for ceramic ball bearings, the local strength of a brittle second phase that serves to reinforce a metal. The method uses focused ion beam milling and a nanoindentation device, and is free of artifacts c ...

Influence of temperature and wetting angle on capillarity in pressure infiltration

Andreas Mortensen, William Craig Carter, Ludger Weber, Alain Léger, Gionata Schneider

Capillary forces in the pressure infiltration process can be quantified by measuring saturation curves; these are plots of the fraction pore space filled with the liquid infiltrant versus the pressure difference between the liquid and the atmosphere initia ...

Magneto-mechanical actuation of ferromagnetic shape memory alloy/epoxy composites

Véronique Michaud, Luis Pablo Canal Casado, Susanne Glock

Ferromagnetic shape memory alloys (MSMA) exhibit magnetic field- and stress-induced twinning when processed into single crystals, but are brittle and difficult to shape. Embedding slender single crystalline MSMA elements into a polymer matrix can thus prov ...

Rational design of fiber-reinforced hybrid composites: A global load sharing analysis

William Curtin, Varun Parameswaran Rajan

An analytical model based on global load sharing (GLS) theory is developed to guide design of fiber-reinforced hybrid composites with superior mechanical properties to single-fiber-type composites. The hybrid is assumed to comprise two types of fibers-low- ...

High-resolution, large-area fabrication of compliant electrodes via laser ablation for robust, stretchable dielectric elastomer actuators and sensors

Herbert Shea, Samuel Rosset

A key element in stretchable actuators, sensors and systems based on elastomer materials are compliant electrodes. While there exist many methodologies for fabricating electrodes on dielectric elastomers, very few succeed in achieve high-resolution pattern ...

Magnesium interatomic potential for simulating plasticity and fracture phenomena

William Curtin, Michael Frederick Francis

Magnesium has multiple dislocation and twinning systems with starkly different properties, which make its plastic deformation strongly anisotropic and highly complex. Existing empirical interatomic potentials fail to capture the full scope of these propert ...
