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…
Gas Diffusion in Cement Pastes: An Analysis using a Fluctuating Diffusivity Model
Fumiaki Nakai, Takato Ishida
This work propose an application of the concept of fluctuating diffusivity to the diffusion of gas molecules in cementitious materials, particularly through a two-state fluctuating…
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…
