Maximum entropy copula with given diagonal section
Cristina Butucea, Jean-François Delmas, Anne Dutfoy +1
We consider copulas with a given diagonal section and compute the explicit density of the unique optimal copula which maximizes the entropy. In this sense, this copula is the least…
Coupling of elasticity to capillarity in soft aerated materials
Lucie Ducloué, Olivier Pitois, Julie Goyon +2
We study the elastic properties of soft solids containing air bubbles. Contrary to standard porous materials, the softness of the matrix allows for a coupling of the matrix elastic…
Demodulation of spatial carrier images : performance analysis of several algorithms using a single image
Claudiu Badulescu, M. Bornert, J. C. Dupré +6
Optical full-field techniques have a great importance in modern experimental mechanics. Even if they are reasonably spread among the university laboratories, their diffusion in ind…
Analysis of Boundary Conditions for Crystal Defect Atomistic Simulations
V. Ehrlacher, C. Ortner, A. V. Shapeev
Numerical simulations of crystal defects are necessarily restricted to finite computational domains, supplying artificial boundary conditions that emulate the effect of embedding t…
Capillary Flow of Oil in a Single Foam Microchannel
Keyvan Piroird, Élise Lorenceau
When using appropriate surfactants, oil and aqueous foam can be intimately mixed without the foam being destroyed. In this Letter, we show that a foam, initially free of oil, can d…
Mixtures of foam and paste: suspensions of bubbles in yield stress fluids
Michael Kogan, Lucie Ducloué, Julie Goyon +3
We study the rheological behavior of mixtures of foams and pastes, which can be described as suspensions of bubbles in yield stress fluids. Model systems are designed by mixing mon…
