Advanced methodology for wind resource assessment near hydroelectric dams in complex mountainous areas
(2019-11-05)
Article
Restricted access - publisher's policyTo increase renewable energy generation in some hydroelectric dams, a solution consisting in installing wind turbines close to dams is proposed. Indeed, dam surroundings are prone to benefit from wind speed-up effect, extra ... -
Combined molecular/continuum modeling reveals the role of friction during fast unfolding of coiled-coil proteins
(2019-05-30)
Article
Restricted access - publisher's policyCoiled-coils are filamentous proteins that form the basic building block of important force-bearing cellular elements, such as intermediate filaments and myosin motors. In addition to their biological importance, coiled-coil ... -
A continuous-discontinuous model for crack branching
(John Wiley & sons, 2019-10-05)
Article
Restricted access - publisher's policyA new continuous-discontinuous model for fracture that accounts for crack branching in a natural manner is presented. It combines a gradient-enhanced damage model based on nonlocal displacements to describe diffuse cracks ... -
Transmission Loss formulas for junctions taking into accountin-plane waves
(2019)
Conference report
Open AccessIn the transmission of vibrations through structural junctions at high frequencies,the distribution of energy between wave types con suffer important variations. It means, for example, that incoming energy concentrated in ... -
Application of inverse SEA models to obtain the Coupling LossFactor in structural junctions from numerical simulations
(2019)
Conference report
Open AccessAn inverse SEA procedure that mimics the Experimental SEA (ESEA) is used in order to obtain the Coupling Loss Factor (CLF) of structural junctions. The main differences with respect to ESEA are that: 1) the subsystem ... -
Multiscale proper generalized decomposition based on the partition of unity
(John Wiley & sons, 2019-11-09)
Article
Restricted access - publisher's policySolutions of partial differential equations could exhibit a multiscale behavior. Standard discretization techniques are constraints to mesh up to the finest scale to predict accurately the response of the system. The ... -
Out-of-equilibrium mechanochemistry and self-organization of fluid membranes interacting with curved proteins
(2019-09-04)
Article
Open AccessThe function of biological membranes is controlled by the interaction of the fluid lipid bilayer with various proteins, some of which induce or react to curvature. These proteins can preferentially bind or diffuse towards ... -
Converse flexoelectricity yields large piezoresponse force microscopy signals in non-piezoelectric materials
(2019-03-20)
Article
Open AccessConverse flexoelectricity is a mechanical stress induced by an electric polarization gradient. It can appear in any material, irrespective of symmetry, whenever there is an inhomogeneous electric field distribution. This ... -
Mechanotransmission of haemodynamic forces by the endothelial glycocalyx in a full-scale arterial model
(2019-06-05)
Article
Open AccessThe glycocalyx has been identified as a key mechano-sensor of the shear forces exerted by streaming blood onto the vascular endothelial lining. Although the biochemical reaction to the blood flow has been extensively ... -
Swimming Euglena respond to confinement with a behavioural change enabling effective crawling
(2019-02-18)
Article
Open AccessSome euglenids, a family of aquatic unicellular organisms, can develop highly concerted, large-amplitude peristaltic body deformations. This remarkable behaviour has been known for centuries. Yet, its function remains ... -
Modelling fluid deformable surfaces with an emphasis on biological interfaces
(2019-08-10)
Article
Restricted access - publisher's policyFluid deformable surfaces are ubiquitous in cell and tissue biology, including lipid bilayers, the actomyosin cortex or epithelial cell sheets. These interfaces exhibit a complex interplay between elasticity, low Reynolds ... -
Automatically imposing incremental boundary displacements for valid mesh morphing and curving
(2019-07)
Article
Open AccessWe present a new incremental mesh morphing method obtained by proposing and discretizing a solution procedure for the continuous morphing problem. Our method seeks a diffeomorphism that transforms an initial domain to a ...
