Stress Drops Associated with Surface Crack Formation in Photo-aged Polypropylene during Three-Point Bending
Kazuya Haremaki, Yusuke Koide, Takashi Uneyama +2
The paper studies how UV‑induced aging creates a depth‑dependent embrittlement in polypropylene, causing discrete stress drops during three‑point bending when the aged surface is u…
A Generalized Mechanical Model for the Cycle Rank Dependence of Stretch at Break in Phantom Chain Star Polymer Networks
Yuichi Masubuchi, Takato Ishida, Takashi Uneyama
A simple mechanical model was recently proposed to explain the universality of stretch at break (λ_b) as a function of cycle-rank density (ξ) in phantom-chain network simulations…
Statistics of rupture in phantom chain network simulations
Yuichi Masubuchi, Takato Ishida, Takashi Uneyama
Phantom chain simulations have shown that the mean rupture properties of star polymer networks collapse onto master curves against the cycle rank density . This study revisits…
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…
