Meso-scale modeling of cohesive cavitation in polymer networks
Saleh Assadi, Zachary T. White, Fay Salmon +6
Cavitation influences the failure of elastomers and soft adhesives, but connecting its microscopic initiation to subsequent cavity growth remains challenging. Here, we develop a di…
How do 3M Command strips work? A fracture mechanics approach
Xue-Ling Luo, Nikolaos Bouklas, Chung-Yuen Hui
Removable adhesive systems such as 3M Command strips are designed to support substantial loads while allowing clean, damage-free removal from the substrate. These systems rely on a…
Modeling cavitation and fibrillation in elastomers and adhesives. Part I: Cohesive instability
S. Mohammad Mousavi, Sarvesh Joshi, Franck Vernerey +1
Cavitation in soft elastomers and adhesives is often viewed as an elastic instability, commonly tied to the study of incompressible solids. It is the first step prior to fibrillati…
Rethinking failure in polymer networks: a probabilistic view on progressive damage
Noy Cohen, Nikolaos Bouklas, Chung-Yuen Hui
The mechanics of single-chain stretching and rupture are central to understanding the resilience of biological polymers and designing strong and tough soft materials such as double…
Instabilities and Phase Transformations in Architected Metamaterials: a Gradient-Enhanced Continuum Approach
Sarvesh Joshi, S. Mohammad Mousavi, Craig M. Hamel +4
Architected metamaterials such as foams and lattices exhibit a wide range of properties governed by microstructural instabilities and emerging phase transformations. Their macrosco…
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…
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…
Multiphysics Modeling of Surface Diffusion Coupled with Large Deformation in 3D Solids
Jaemin Kim, Keon Ho Kim, Nikolaos Bouklas
We present a comprehensive theoretical and computational model that explores the behavior of a thin hydrated film bonded to a non-hydrated / impermeable soft substrate in the conte…
Modeling the mechanosensitive collective migration of cells on the surface and the interior of morphing soft tissues
Jaemin Kim, Mahmut Selman Sakar, Nikolaos Bouklas
Cellular contractility, migration, and extracellular matrix (ECM) mechanics are critical for a wide range of biological processes including embryonic development, wound healing, ti…
A finite element implementation of finite deformation surface and bulk poroelasticity
Jaemin Kim, Ida Ang, Francesco Ballarin +2
We present a theoretical and computational model for the behavior of a porous solid undergoing two interdependent processes, the finite deformation of a solid and species migration…
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…
Machine-learning convex and texture-dependent macroscopic yield from crystal plasticity simulations
Jan N. Fuhg, Lloyd van Wees, Mark Obstalecki +3
The influence of the microstructure of a polycrystalline material on its macroscopic deformation response is still one of the major problems in materials engineering. For materials…
X-ray nanoimaging of crystal defects in single grains of solid-state electrolyte AlxLi7-3xLa3Zr2O12
Yifei Sun, Oleg Yu. Gorobstov, Linqin Mu +6
All-solid-state lithium batteries promise significant improvements in energy density and safety over traditional liquid electrolyte batteries. The Al-doped AlxLi7-3xLa3Zr2O12 (LLZO…
