The ability of cells to orient in response to mechanical stimuli is essential to embryonic development, cell migration, mechanotransduction, and other critical physiologic functions in a range of… (More)
Abstract It is shown that second-order homogenization of a Cauchy-elastic dilute suspension of randomly distributed inclusions yields an equivalent second gradient (Mindlin) elastic material. This… (More)
Abstract Starting from a Cauchy elastic composite with a dilute suspension of randomly distributed inclusions and characterized at first-order by a certain discrepancy tensor (see part I of the… (More)
A viscoelastic constitutive law is developed for a hydrogel to encompass deviatoric deformations where the viscosity of the solvent contributes to the deviatoric stress of the system. The law is… (More)
The design of periodic and quasiperiodic structures possessing innovative filtering properties for elastic waves opens the way to the realization of elastic metamaterials. In these structures… (More)
Abstract The homogenization results obtained by Bacca et al. (2013a) , to identify the effective second-gradient elastic materials from heterogeneous Cauchy elastic solids, are extended here to the… (More)
Abstract Severe plastic deformation (strains > 100%) has been shown to create significant grain refinement in polycrystalline materials, leading to a nanometric equiaxed crystalline structure for… (More)
It is shown that second-order homogenization of a Cauchy-elastic dilute suspension of inclusions yields an equivalent second gradient (Mindlin) elastic material. This result is valid for both plane… (More)
