Primitive Chain Network Simulations of Entangled Melts of Symmetric and Asymmetric Star Polymers in Uniaxial Elongational Flows
Yuichi Masubuchi, Giovanni Ianniruberto, Giuseppe Marrucci
Ianniruberto and Marrucci developed a theory whereby entangled branched polymers behave like linear ones in fast elongational flows. In order to test such prediction, Huang et al.…
Plateau Moduli of Several Single-Chain Slip-Link and Slip-Spring Models
Takashi Uneyama, Yuichi Masubuchi
We calculate the plateau moduli of several single-chain slip-link and slip-spring models for entangled polymers. In these models, the entanglement effects are phenomenologically mo…
Wall slip in primitive chain network simulations of shear startup of entangled polymers and its effect on the shear stress undershoot
Yuichi Masubuchi, Dimitris Vlassopoulos, Giovanni Ianniruberto +1
In some recent experiments on entangled polymers of stress growth in startup of fast shear flows an undershoot in the shear stress is observed following the overshoot, i.e., before…
Multi-chain slip-spring simulations with various slip-spring densities
Yuichi Masubuchi, Yuya Doi, Takashi Uneyama
Although it has been established that the multi-chain slip-spring (MCSS) model can reproduce entangled polymer dynamics, the effects of model parameters have not been fully elucida…
Short time dynamics of tracer in ideal gas
Fumiaki Nakai, Yuichi Masubuchi, Takashi Uneyama
A small tagged particle immersed in a fluid exhibits the Brownian motion and diffuses at the long-time scale. Meanwhile, at the short-time scale, the dynamics of the tagged particl…
Effect of Inertia on Linear Viscoelasticity of Harmonic Dumbbell Model
Takashi Uneyama, Fumiaki Nakai, Yuichi Masubuchi
The overdamped (inertialess) dumbbell model is widely utilized to study rheological properties of polymers or other soft matters. In most cases, the effect of inertia is merely neg…
