Phantom chain simulations for the effect of stoichiometry on the fracture of star-polymer networks
Yuichi Masubuchi
By phantom chain simulations, it has been recently discovered that the fracture characteristics of star polymer networks with different node functionality and conversion ratios can…
Modeling for heterogeneous oxidative aging of polymers using coarse-grained molecular dynamics
Takato Ishida, Yuya Doi, Takashi Uneyama +1
This study presents a coarse-grained molecular dynamics simulation model to investigate the process of oxidative aging in polymers. The chemical aging effect is attributed to the a…
Phantom-Chain Simulations for the Effect of Node Functionality on the Fracture of Star-Polymer Networks
Yuichi Masubuchi, Yuya Doi, Takato Ishida +5
The influence of node functionality (f) on the fracture of polymer networks remains unclear. While many studies have focused on multi-functional nodes with f>4, recent research sug…
Extension of Moving Particle Simulation including rotational degrees of freedom for dilute fiber suspension
Keigo Enomoto, Takato Ishida, Yuya Doi +2
We develop a novel Moving Particle Simulation (MPS) method to accurately reproduce the motion of fibers floating in sheared liquids. In conventional MPS schemes, if a fiber suspend…
Increase in rod diffusivity emerges even in Markovian nature
Fumiaki Nakai, Martin Kröger, Takato Ishida +3
Rod-shaped particles embedded in certain matrices have been reported to exhibit an increase in their center of mass diffusivity upon increasing the matrix density. This increase ha…
High-pressure BaCN phases explored by genetic algorithm
Peng Song, Mari Kawaguchi, Yuji Masubuchi +4
Polymers containing nitrogen have attracted much attention in connection with their application to high energy density materials (HEDMs), in which energy is inherent in the triple…
Fluctuating Diffusivity Emerges even in Binary Gas Mixtures
Fumiaki Nakai, Yuichi Masubuchi, Yuya Doi +2
Diffusivity in some soft matter and biological systems changes with time, called the fluctuating diffusivity. In this work, we propose a novel origin for fluctuating diffusivity ba…
Stress Tensor of Single Rigid Dumbbell by Virtual Work Method
Takashi Uneyama, Tatsuma Oishi, Takato Ishida +2
We derive the stress tensor of a rigid dumbbell by using the virtual work method. In the virtual work method, we virtually apply a small deformation to the system, and relate the c…
Elasticity of randomly cross-linked networks in primitive chain network simulations
Yuichi Masubuchi
Primitive chain network simulations for randomly cross-linked slip-link networks were performed. For the percolated networks, the stress-strain relationship was compared to the the…
Multi-chain Slip-spring Model for Entangled Polymer Dynamics
Takashi Uneyama, Yuichi Masubuchi
It has been established that the entangled polymer dynamics can be reasonably described by single chain models such as tube and slip-link models. Although the entanglement effect i…
Detailed Balance Condition and Effective Free Energy in the Primitive Chain Network Model
Takashi Uneyama, Yuichi Masubuchi
We consider statistical mechanical properties of the primitive chain network (PCN) model for entangled polymers from its dynamic equations. We show that the dynamic equation for th…
