Invariant fractocohesive length in thermally aged elastomers
Aimane Najmeddine, Santiago Marin, Zhen Xu +3
The fractocohesive length - the ratio between fracture toughness and work-to-fracture - provides a material-specific length scale that characterizes the size-dependent fracture beh…
Predicting Stress and Damage in Carbon Fiber-Reinforced Composites Deformation Process using Composite U-Net Surrogate Model
Zeping Chen, Marwa Yacouti, Maryam Shakiba +3
Carbon fiber-reinforced composites (CFRC) are pivotal in advanced engineering applications due to their exceptional mechanical properties. A deep understanding of CFRC behavior und…
Physics and chemistry-based constitutive framework for thermo-chemically aged elastomer using phase-field approach
Aimane Najmeddine, Maryam Shakiba
We propose a physics and chemistry-based constitutive framework to predict the stress responses of thermo-chemically aged elastomers and capture their brittle failure using the pha…
Physics-based Constitutive Modeling of Photo-oxidative Aging in Semi-Crystalline Polymers based on Chemical Characterization Techniques
Aimane Najmeddine, Zhen Xu, Guoliang Liu +2
This paper proposes a physio-chemically-based constitutive framework to simulate and predict the response of semi-crystalline low-density polyethylene (LDPE) to severe photo-oxidat…
Physics-based Constitutive Equation for Thermo-Chemical Aging in Elastomers based on Crosslink Density Evolution
Maryam Shakiba, Aimane Najmeddine
This paper presents a physics-based constitutive equation to predict the thermo-chemical aging in elastomers. High-temperature oxidation in elastomers is a complex phenomenon. The…
A Data-Driven Approach to Full-Field Damage and Failure Pattern Prediction in Microstructure-Dependent Composites using Deep Learning
Reza Sepasdar, Anuj Karpatne, Maryam Shakiba
An image-based deep learning framework is developed in this paper to predict damage and failure in microstructure-dependent composite materials. The work is motivated by the comple…
Overcoming the Convergence Difficulty of Cohesive Zone Models through a Newton-Raphson Modification Technique
Reza Sepasdar, Maryam Shakiba
This paper studies the convergence difficulty of cohesive zone models in static analysis. It is shown that an inappropriate starting point of iterations in the Newton-Raphson metho…
