Orientational origin of nonlinear shear rheology in unentangled polymer melts
Souta Miyamoto, Takeshi Sato, John J. Molina +1
Universal rheological properties of unentangled polymer melts are investigated through the stretch-orientation decomposition of polymer dynamics. By externalizing stretch from the…
Polymer viscoelasticity from an orientational closure with implicit stretch
Souta Miyamoto, Takeshi Sato, Wanxiang Jin +3
We propose a deviatoric-stress constitutive equation derived from orientational kinetics, while implicitly retaining contributions from conformational stretch. Starting from the du…
A deviatoric-stress closure for constitutive modeling of viscoelastic dynamics
Souta Miyamoto, Shotaro Moro, Takeshi Sato +4
Standard rheological measurements yield only selected stress components; thus, inferring tensorial constitutive equations from experimentally accessible observables is complicated.…
Rheo-SINDy: Finding a Constitutive Model from Rheological Data for Complex Fluids Using Sparse Identification for Nonlinear Dynamics
Takeshi Sato, Souta Miyamoto, Shota Kato
Rheology plays a pivotal role in understanding the flow behavior of fluids by discovering governing equations that relate deformation and stress, known as constitutive equations. D…
