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…
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…
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…
Phantom chain simulations for fracture of star polymer networks on the effect of arm molecular weight
Yuichi Masubuchi
This study investigated the fracture of star polymer networks made from prepolymers with various arm molecular weights in the range , for node functionalities $3…
