Effect of Pre-straining, Activation Temperature and Thermomechanical Training on Recovery Behavior of Femnsi Based Sma

Iron-based shape memory alloys (Fe-SMAs) can be used for strengthening of existing concrete structures in civil and architectural engineering. This study investigates the recovery behavior of Fe-SMAs under varying pre-strain levels, activation temperatures ...

Influence of model uncertainty and long term deformations in action effects calculation in reinforced concrete structures

Xhemsi Malja

Most codes of practice adopt a semi probabilistic design approach for the dimensioning and assessment of structures. Accordingly, structural safety is ensured by performing limit state verifications using design values determined with adequately calibrated ...

On the slip burst amplitude cutoff in dislocation-rich microcrystals

Andreas Mortensen, Luciano Borasi

The plastic deformation of small-scale face-centered cubic metals exhibits intermittent slip burst events that appear on stress-strain curves as sudden strain jumps and/or load drops. These events are generally attributed to the avalanche-like cooperative ...

Elastic limit tensile stress of UHPFRC: Method of determination and effect of fiber orientation

Eugen Brühwiler, Emmanuel Denarié, Jian Zhan

This paper discusses the influence of fiber orientation on elastic limit tensile stress of ultra-high performance fiber reinforced cementitious composites (UHPFRC). An original model relating elastic limit tensile stress to fiber orientation is proposed, a ...

Controlling superconductivity of CeIrIn5 microstructures by substrate selection

Philip Johannes Walter Moll, Matthias Carsten Putzke, Chunyu Guo, Maarten Ruud van Delft, Joshua Alan Wolfe Straquadine

Superconductor/metal interfaces are usually fabricated in heterostructures that join these dissimilar materials. A conceptually different approach has recently exploited the strain sensitivity of heavy-fermion superconductors, selectively transforming regi ...

Yielding of a quartz sand from saturated to dry state

Alessio Ferrari

The paper presents the results of an experimental work where we analyse the behaviour of an unsaturated quartz sand in a wide range of degree of saturation (from saturated to dry state). The possibility of anticipating the hydro-mechanical behaviour of the ...

Solute-dislocation interactions and creep-enhanced Cu precipitation in a novel ferritic-martensitic steel

Roland Logé, Cyril Cayron

G115 steel has gained a growing interesting recently for its use in next-generation ultra-supercritical power plant applications. Due to the high densities of dislocations and lath martensite boundaries in G115 steel, interactions between solutes and dislo ...

In situ characterization of work hardening and springback in grade 2 alpha-titanium under tensile load

Helena Van Swygenhoven

Plastic effects during sheet metal forming can lead to undesirable distortions in formed components. Here, the three-stage work hardening and plastic strain recovery ("springback") in a cold-rolled, alpha-phase commercially pure titanium is examined. Inter ...

Electrical energy generated by silicone elastomers filled with nanospring- carbon- nanotubes

Frank Nüesch

Dielectric elastomer generators (DEGs) are flexible capacitors that convert mechanical into electrical energy. They rely on an external voltage source to charge the capacitor during each operation cycle. An alternative to this is an autonomous DEG which op ...

Next generation UHPFRC for sustainable structural applications

Emmanuel Denarié, Amir Hajiesmaeili

Over the last few decades, ever-increasing demands of society to the built environment have continually increased consumption of energy and materials for the construction and maintenance of structures. Meanwhile, Strain Hardening Ultra High-Performance Fib ...

Cast aluminium microwires : processing and plastic deformation

Jérôme Krebs

Plasticity size effects have been the focus of strong recent interest due to the miniaturization of devices such as actuators and different medical apparatuses. Devices with a sub-micrometre dimension have a high market potential and therefore a thorough u ...

A Review of Dynamic Experimental Techniques and Mechanical Behaviour of Rock Materials

Jian Zhao, Qianbing Zhang

The purpose of this review is to discuss the development and the state of the art in dynamic testing techniques and dynamic mechanical behaviour of rock materials. The review begins by briefly introducing the history of rock dynamics and explaining the sig ...

Plastic and Elastic Strain Fields in GaAs/Si Core-Shell Nanowires

Christophe Ballif, Anna Fontcuberta i Morral, Martin Heiss, Sylvain Dunand, Eleonora Russo, Sonia Conesa Boj

Thanks to their unique morphology, nanowires have enabled integration of materials in a way that was not possible before with thin film technology. In turn, this opens new avenues for applications in the areas of energy harvesting, electronics, and optoele ...

Tensile elongation of unidirectional or laminated composites combining a brittle reinforcement with a ductile strain and strain-rate hardening matrix

Andreas Mortensen, Amaël Maximilien Cohades

We use the long-wavelength model of Hutchinson and Neale (1977) and Ghosh (1977) to estimate the uniform tensile elongation of two-phase composites deforming quasistatically according to the equistrain rule of mixtures, in which one phase is ductile while ...
