Design of experiments to investigate multi-additive cellulose nanocrystal films

Cellulose nanocrystal (CNC) suspensions can self-assemble into chiral nematic films upon the slow evaporation of water. These films are brittle, as indicated by their fracturing instead of plastically deforming once they are fully elastically deformed. Thi ...

Inferring the flow properties of epithelial tissues from their geometry

Matthieu Wyart, Marko Popovic, Valentin Camille Druelle

Amorphous materials exhibit complex material properties with strongly nonlinear behaviors. Below a yield stress they behave as plastic solids, while they start to yield above a critical stress sigma(c). A key quantity controlling plasticity which is, howev ...

Adhesive wear of rough surfaces and interaction of micro-contacts

Son-Jonathan Pham-Ba

The tribological interaction between two rough surfaces comes down to the contact of microscale asperities, forming micro-contacts. Recent work demonstrated the existence of a critical asperity size d* governing a ductile-to-brittle transition for a given ...

Adhesive wear mechanisms in the presence of weak interfaces: Insights from an amorphous model system

Jean-François Molinari, Tobias Brink

Engineering wear models are generally empirical and lack connections to the physical processes of debris generation at the nanoscale to microscale. Here, we thus analyze wear particle formation for sliding interfaces in dry contact with full and reduced ad ...

Crack Nucleation in the Adhesive Wear of an Elastic-Plastic Half-Space

Jean-François Molinari, Guillaume Anciaux, Lucas Henri Galilée Frérot

The detachment of material in an adhesive wear process is driven by a fracture mechanism which is controlled by a critical length-scale. Previous efforts in multi-asperity wear modeling have applied this microscopic process to rough elastic contact. Howeve ...

Simulation of the welding process of steel tube joints made of S355 and S690

Janna Krummenacker

Welding is an important joining method for the work with metals. During the welding process, the material is heated and deforms plastically which leads a change in microstructure in the heat affected zone, to complex residual stress distributions, and dist ...

Origin of intragranular crystallographic misorientations in hot-dip Al-Zn-Si coatings

Johann Michler, Alain Jacot, Christoph Niederberger

The origin of intragranular variations of the crystallographic orientation in hot-dip Al-Zn-Si coatings is discussed based on new experimental results and modelling. The solidification microstructure in as-received 55Al-43.4Zn-l.6Si (in wt.%) coatings depo ...

Experimental study of Ni3Al slip traces by atomic force microscopy: an evidence of mobile dislocation exhaustion

Joël Bonneville

Slip markings produced on the surfaces of Ni3(Al, Ta) single crystals, plastically deformed at various temperatures in the flow stress anomaly domain, were examined by atomic force microscopy (AFM). A dominant feature is that for all investigated temperatu ...

Low-profile mechanisms in composites with thermoplastic/polyester blend matrices

Unsaturated Polyester (UP) resins are extensively used as a matrix for the production of composites due to their low cost and versatility. Their significant polymerization shrinkage has however a negative impact on the dimensional stability of the molded p ...

Local annealing of shape memory alloys using laser scanning and computer vision

René Salathé, Yves Bellouard, Reymond Clavel, Thomas Sidler, Moustapha Hafez

A complete set-up for local annealing of Shape Memory Alloys (SMA) is proposed. Such alloys, when plastically deformed at a given low temperature, have the ability to recover a previously memorised shape simply by heating up to a higher temperature. They f ...
