A direct theory of strain-gradient special Cosserat rods via the principle of virtual work
R. S. Hallyburton, C. Rodriguez
Motivated by recent advances in the synthesis of effective one-dimensional mechanical metamaterials, we develop a direct theory of strain-gradient special Cosserat rods based on th…
Coexisting Tayler instability-driven dynamos in radiative zones: New dynamo solution and its impacts on stellar physics
Paul Barrère, Alexis Reboul-Salze, Patrick Eggenberger +3
Recent asteroseismic observations constitute a great challenge for rotating stellar evolution models, which predict overly fast internal rotation rates when only hydrodynamic proce…
Shell energies derived from three-dimensional isotropic strain-gradient elasticity
C. Balitactac, Y. Canzani, R. S. Hallyburton +2
We derive a class of two-dimensional shell energies for thin elastic bodies exhibiting small-length scale effects modeled via strain-gradient elasticity. Building on the final auth…
Inclined flow of a second-gradient incompressible fluid with pressure-dependent viscosity
C. Balitactac, C. Rodriguez
Many viscous liquids behave effectively as incompressible under high pressures but display a pronounced dependence of viscosity on pressure. The classical incompressible Navier-Sto…
