Sensitivity of cohesive zone models in CFRP delamination modeling
Theoretical and Applied Fracture Mechanics[EN] Composite laminates such as carbon fiber reinforced polymers (CFRPs) are highly susceptible to delamination damage, which is considered one of the most important failure mechanisms in this type of material. In this work, a parametric study of one of the most used numerical methods to simulate this type of fracture is developed: the cohesive zone ...

Numerical implementation of a cohesive zone model for time and history dependent materials [PDF]
, 2014 This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.A cohesive zone model approach is used in order to study the behaviour of cracks in elasto-plastic materials. The cohesive zone model being studied is time-

Engineering Fracture MechanicsDelamination is a critical mode of failure that occurs between plies in a composite laminate. The cohesive element, developed based on the cohesive zone model, is widely used for modeling delamination. However, standard cohesive elements suffer from a well-known limit on the mesh density-the element size must be much smaller than the cohesive zone size.

Advanced Healthcare Materials, EarlyView.This review examines how cellular behavior is regulated by mechanical cues transmitted through soft biomaterials, from single‐cell mechanosensing to tissue‐level adaptation. It highlights why physiological relevance, rather than model complexity alone, is critical for translational mechanobiology and introduces a scoring framework linking material ...

Measuring and understanding biogenic influences upon cohesive sediment stability in intertidal systems [PDF]
, 2010 Intertidal cohesive sediment systems are found throughout the world in areas of low hydrodynamic energy. These systems are ecologically and economically important but are under pressure from global warming, sea level rise and other anthropogenic ...

Advanced Healthcare Materials, EarlyView.Gellan gum fluid gel (FG) enables controlled ocular delivery of mesenchymal stromal cell (MSC)‐derived extracellular vesicles (EV). Its shear‐thinning, solid‐liquid‐solid rheology ensures prolonged ocular retention. Sustained MSC‐EV release (∼18% in 6 hrs) supports effective EV ocular delivery.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics
Advanced Materials, EarlyView.The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Numerical simulation of stable fatigue crack growth rate using a cohesive zone model [PDF]
, 2012 Predicting the remaining fatigue life of a structure with crack(s) is generally conducted by the fracture mechanics method. This method is aimed at predicting the crack growth and final fracture due to fluctuating loads.
