Effect of flow kinematics on extensional viscosity of dilute polymer solutions
Yusuke Koide, Takato Ishida, Takashi Uneyama +1
We investigate the effect of flow kinematics on the extensional viscosity of dilute polymer solutions by conducting dissipative particle dynamics simulations under uniaxial, planar…
Coarse-Grained Molecular Dynamics Simulations of Oxidative Aging and Stabilization in Polymer Melts with Primary Antioxidants: Effects of Antioxidant Concentration and Molecular Architecture
Takato Ishida, Emmanuel Richaud
Industrial polymeric materials often rely on antioxidants to achieve long-term reliability. Previous studies have frequently discussed the stabilization effect in the presence of m…
Relation between extensional viscosity and polymer conformation in dilute polymer solutions
Yusuke Koide, Takato Ishida, Takashi Uneyama +1
We investigate extensional viscosity and polymer conformation in dilute polymer solutions under uniaxial extensional flow using dissipative particle dynamics simulations. At high e…
A Review on Molecular Simulations for the Rupture of Polymer Networks
Yuichi Masubuchi, Takato Ishida, Yusuke Koide +1
Molecular simulations provide a powerful means to unravel the complex relationships between network architecture and the mechanical response of polymer networks, with a particular…
Influence of Stretching Boundary Conditions on Fracture in Phantom Star Polymer Networks: From Volume to Cross-sectional Area Conservation
Yuichi Masubuchi, Takato Ishida, Yusuke Koide +1
This study systematically investigates the effect of stretching boundary conditions, ranging from conservation of cross-sectional area to conservation of volume, on the rupture beh…
Steady-state extensional viscosity of wormlike micellar solutions via dissipative particle dynamics simulations
Yusuke Koide, Takato Ishida, Takashi Uneyama +1
We investigate the steady-state extensional viscosity of wormlike micellar solutions using dissipative particle dynamics simulations. As the extension rate increases, the steady-st…
