Multi-scale modeling of elasto-plastic response of SnAgCu lead-free solder alloys at different ageing conditions: Effect of microstructure evolution, particle size effects and interfacial failure

John Botsis, Joël Cugnoni, Milad Maleki

In microelectronics applications, SnAgCu lead-free solder joints play the important role of ensuring both the mechanical and electrical integrity of the components. In such applications, the SnAgCu joints are subjected to elevated homologous temperatures f ...

Rayleigh-Taylor instability under curved substrates: An optimal transient growth analysis

François Gallaire, Gioele Mariano Nicolò Balestra, Pierre-Thomas Paul Brun

We investigate the stability of thin viscous films coated on the inside of a horizontal cylindrical substrate. In such a case, gravity acts both as a stabilizing force through the progressive drainage of the film and as a destabilizing force prone to form ...

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 ...
