Analysis and prediction of fatigue crack growth performance for fiber reinforced aluminum-lithium alloy laminates under single-peak compressive overload

Journal of Aeronautical Materials
As a new type of aviation material，fiber/aluminum-lithium（Al-Li）laminates are significantly threatened by fatigue cracks. In other words，fatigue cracks are the “fatal killers”，which leads to their failure.

Tough Injectable Hydrogels Enabled by Integrating Rigid Homogeneous Framework With Flexible Chains

Advanced Functional Materials, EarlyView.
Tough injectable hydrogels are constructed by integrating a rigid, homogeneous hyaluronic acid framework with flexible long‐chain connectors. This framework–flexible structure simultaneously enhances network uniformity and promotes effective energy dissipation by enlarging plastic deformation zones under compression.

Fatigue crack growth in polymers

Polymer Testing, 2001
Within the framework of fracture mechanics the fatigue of polymers is characterised by the rate of crack propagation as a function of the amplitude and frequency of the stress intensity factor. The measurements are performed by starting with a notched specimen to be independent of inherent natural or surface defects.

Electrode and Microstructure Dependence of Oxygen Diffusion in Ferroelectric Hafnium Zirconium Oxide Thin Films

Advanced Functional Materials, EarlyView.
Significant nanoscale oxygen diffusion coefficient variations are measured in ferroelectric hafnium zirconium oxide films with grain boundaries and electrode interfaces exhibiting values 104 times larger than the grain cores. Overall coefficients are 10X larger for films prepared with metal nitride electrodes compared to refractory metals. New insights
