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…
