Extensible links in a broad class of single polymer chain models
Michael R. Buche, Matthew J. Grasinger, Jason P. Mulderrig
The physics of polymer chains is often probed using molecular stretching experiments and various idealized single-chain models. The majority of these models consist of a discrete s…
Capturing the fractocohesive length scale through a gradient-enhanced damage model for elastomers
S. Mohammad Mousavi, Jason Mulderrig, Brandon Talamini +1
This study aims to unravel the micro-mechanical underpinnings of the emergence of the fractocohesive length scale as a central concept in modern fracture mechanics. A thermodynamic…
Polydisperse polymer networks with irregular topologies: Mechanics of cross-link distributions
Jason Mulderrig, Michael Buche, Matthew Grasinger
The structure of polymer networks, defined by chain lengths and connectivity patterns, fundamentally influences their bulk properties. While existing polymer network models connect…
A chain stretch-based gradient-enhanced model for damage and fracture in elastomers
S. Mohammad Mousavi, Jason Mulderrig, Brandon Talamini +1
In this study, we introduce a novel stretch-based gradient-enhanced damage (GED) model that allows the fracture to localize and also captures the development of a physically diffus…
Evaluating fracture energy predictions using phase-field and gradient-enhanced damage models for elastomers
S. Mohammad Mousavi, Ida Ang, Jason Mulderrig +1
Recently, the phase field method has been increasingly used for brittle fractures in soft materials like polymers, elastomers, and biological tissues. When considering finite defor…
A statistical mechanics framework for polymer chain scission, based on the concepts of distorted bond potential and asymptotic matching
Jason Mulderrig, Brandon Talamini, Nikolaos Bouklas
To design increasingly tough, resilient, and fatigue-resistant elastomers and hydrogels, the relationship between controllable network parameters at the molecular level to macrosco…
