Quasistatic nonlinear viscoelasticity and gradient flows
(Springer Science+Business Media, 2014)We consider the equation of motion for one-dimensional nonlinear viscoelasticity of strain-rate type under the assumption that the stored-energy function is λ-convex, which allows for solid phase transformations. We formulate ... -
First lattice calculation of charmed hadrons' electromagnetic form factors
(IOP Publishing, 2014)Electromagnetic form factors of D and D* mesons and Ξcc, Σc, Ωc and Ωcc baryons are calculated in 2+1 flavor lattice QCD. As a by product of this calculation electric/magnetic charge radii and magnetic moments are extracted. ... -
An approach to nonlinear viscoelasticity via metric gradient flows
(SIAM, 2014)We formulate quasistatic nonlinear finite-strain viscoelasticity of rate type as a gradient system. Our focus is on nonlinear dissipation functionals and distances that are related to metrics on weak diffeomorphisms and ... -
