Identifying the Threshold Chain Length for Stress Overshoot in Ring-Linear Polymer Blends under Uniaxial Elongation: The Role of Multiple Threading
Takahiro Murashima, Katsumi Hagita, Toshihiro Kawakatsu
The rheological behavior of ring-linear polymer blends under uniaxial elongational flow has remained a subject of intense debate, particularly regarding the emergence of stress ove…
Butterfly Patterns for Stretched Inhomogeneous Gel Networks using Large-Scale Molecular Dynamics Simulations
Katsumi Hagita, Takahiro Murashima
Large-scale coarse-grained molecular dynamics simulations of inhomogeneous gel networks were performed to investigate abnormal butterfly patterns in two-dimensional scattering. The…
Topological transition in multicyclic chains with structural symmetry inducing stress-overshoot phenomena in multicyclic/linear blends under biaxial elongational flow
Takahiro Murashima, Katsumi Hagita, Toshihiro Kawakatsu
Blends of multicyclic and linear polymers under biaxial elongational flow were analyzed using coarse-grained molecular dynamics simulations. The multicyclic/linear blends displayed…
Viscosity Overshoot in Biaxial Elongational Flow: Coarse-Grained Molecular Dynamics Simulation of Ring-Linear Polymer Mixtures
T. Murashima, K. Hagita, T. Kawakatsu
Viscosity overshoot of entangled polymer melts has been observed under shear flow and uniaxial elongational flow, but has never been observed under biaxial elongational flow. We co…
Coupling Finite Element Method with Large Scale Atomic/Molecular Massively Parallel Simulator (LAMMPS) for Hierarchical Multiscale Simulations
Takahiro Murashima, Shingo Urata, Shaofan Li
In this work, we have developed a multiscale computational algorithm to couple finite element method with an open source molecular dynamics code --- the Large scale Atomic/Molecula…
Elongational viscosity of weakly entangled polymer melt via coarse-grained molecular dynamics simulation
Takahiro Murashima, Katsumi Hagita, Toshihiro Kawakatsu
We investigated the elongational flows of the weakly entangled linear polymer melt using a coarse-grained molecular dynamics simulation. We extended the uniform extensional flow (U…
