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.…
Development of Rheological Constitutive Modeling Method Using a Sparse Identification Algorithm: A Case Study for Extensional Flows
Takeshi Sato, Souta Miyamoto, Shota Kato
Deriving constitutive models (CMs) from numerical data has been an attractive approach as a systematic CM building method. One recent study is Rheo-SINDy, which extended the sparse…
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…
Enhancement of Curie temperature due to the coupling between Fe itinerant electrons and Dy localized electrons in DyFe2Zn20
Yosikazu Isikawa, Toshio Mizushima, Souta Miyamoto +6
The temperature dependence of magnetization and specific heat of the ferromagnetic compound DyFe2Zn20 has been measured in detail in various magnetic fields. We have observed anoma…
