Slip-link simulations of long-fiber networks under uniaxial compression
Yuichi Masubuchi
A coarse-grained molecular simulation approach originally developed for entangled polymeric liquids is extended to model the mechanical behavior of long-fiber networks. The model,…
Developments in Multi-Chain Coarse-Grained Models for Entangled Polymer Dynamics
Yuichi Masubuchi
This review describes the development and applications of multi-chain coarse-grained simulations for entangled polymer dynamics. The mean-field tube model has long served as the st…
Universal Scaling of Macroscopic Softening and Microscopic Scission in Phantom Chain Networks
Yuichi Masubuchi
This study demonstrates that the apparent complexity of fracture in phantom-chain polymer networks is fully decoupled into two universal master curves: (i) macroscopic softening go…
A Toy Model for the Cycle Rank Dependence of Stretch at Break in Phantom Chain Network Simulations
Yuichi Masubuchi
The relationship between the topological architecture of polymer networks and their macroscopic rupture remains a fundamental challenge in polymer physics. Recent coarse-grained si…
Primitive chain network simulations of the creep of entangled polymers
Yuichi Masubuchi, Giovanni Ianniruberto, Giuseppe Marrucci
Although the behavior of entangled polymers in startup shear flows with constant shear rates has been thoroughly investigated, the response under creep has not been frequently cons…
Persistence length and plateau modulus of semiflexible entangled polymers in primitive chain network simulations
Yuichi Masubuchi, Manlio Tassieri, Giovanni Ianniruberto +1
The relationship between the plateau modulus (G_0) and the persistence length (L_p) of entangled semiflexible polymers is still uncertain. Some previous theoretical models have pre…

Phantom chain simulations for fracture of star polymer networks with various strand densities
Yuichi Masubuchi, Takato Ishida, Yusuke Koide +1
Despite many attempts, the relation between fracture and structure of polymer networks is yet to be clarified. For this problem, a recent study for phantom chain simulations [Macro…
Primitive chain network simulations for double peaks in shear stress under fast flows of bidisperse entangled polymers
Yuichi Masubuchi
A few experiments have reported that the time development of shear stress under fast start-up shear deformations exhibits double peaks before reaching the steady state for bimodal…
Phantom Chain Simulations for Fracture of End-linking Networks
Yuichi Masubuchi
Despite numerous studies, the relationship between network structure and fracture remains unclear. In this study, the fracture properties of end-linking networks were compared with…
Anisotropy of shear relaxation in primitive chain network simulations for entangled polymers confined between flat walls
Yuichi Masubuchi
Anisotropic shear relaxation is an interesting but rarely discussed issue in polymer dynamics under confinement [Abberton et al., Macromolecules, 48, 7631, 2015]. According to the…
Phantom chain simulations for fracture of polymer networks created from star polymer mixtures of different functionalities
Yuichi Masubuchi
Fujiyabu et al. have experimentally reported that mixing of 3-arm star prepolymers into 4-arm analog improves the toughness of the resultant polymer networks compared to the base n…
