Microfluidic device combining hydrodynamic and dielectrophoretic trapping for the controlled contact between single micro-sized objects and application to adhesion assays

Philippe Renaud, Arnaud Bertsch, Clémentine Sophie Sarah Lipp

The understanding of cell-cell and cell-matrix interactions via receptor and ligand binding relies on our ability to study the very first events of their contact. Of particular interest is the interaction between a T cell receptor and its cognate peptide-m ...

Computational micromechanics of porous brittle solids

Johan Alexandre Philippe Gaume, Henning Löwe, Lars Kristoffer Uhlen Blatny

Porous brittle solids evidence complex mechanical behavior, where localized failure patterns originate from mechanical processes on the microstructural level. In order to investigate the failure mechanics of porous brittle solids, we outline a general stoc ...

Analysis of the interaction factor method for energy pile groups with slab

Lyesse Laloui, Melis Sütman, Elena Ravera

The design of energy pile is hampered by the complex interaction between the piles and the slab subjected to thermal loads. Although finite element analysis is used to account explicitly for the interactions, this method is mainly considered as a research ...

Elastic Coupling between Nonferroelastic Domain Walls

Nava Setter, Alexander Tagantsev, Petr Yudin, Konstantin Shapovalov

We reveal a strong elastic interaction between nonferroelastic domain walls in ferroelectric thin films. This interaction, having no analogue in bulk materials, is governed by elastic fields that are associated with the domain walls and extends to distance ...

Modelling Plasticity in Nanoscale Contact

Till Junge

The problem of mechanical contact is a truly multiscale one. Atomistic effects that violate continuum theory dominate the deformations of contacting asperities, while the interactions between distant asperities occur through long-range elasticity. This the ...

Two-phase modelling of hot tearing in aluminium alloys using a semi-coupled method

Vincent Mathier

Hot tearing is one of the most severe defects observed in castings, e.g. in billets or sheet ingots of aluminum alloys produced by DC casting. It is due to both tensile strains and a lack of interdendritic feeding in the mushy zone. In order to predict thi ...
