Unraveling Pre-filled Syringe Needle Clogging: Exploring a Fresh Outlook Through Innovative Techniques
This study aimed to investigate the movement of liquid in the needle region of staked-in-needle pre-filled syringes using neutron imaging and synchrotron X-ray tomography. The objective was to gain insights in...

Open AccessCrack nucleation criterion and its application to impact indentation in glasses
Molecular dynamics (MD) simulations are used to directly observe nucleation of median cracks in oxide glasses under indentation. Indenters with sharp angles can nucleate median cracks in samples with no pre-ex...

High-speed camera study of Stage III crack propagation in chemically strengthened glass
Thermally or chemically strengthened glass is more resistant to damage and breakage compared to non-strengthened glass. Both strengthening mechanisms are based on incorporation of a compressive stress profile ...

A Scaled Model Describing the Rate-Dependent Compressive Failure of Brittle Materials
A universal relationship is developed that describes the rate-dependent compressive strength of brittle solids based on the micromechanics of the growth of brittle cracks from populations of initial flaws. Rea...

The Mechanical Response of Aluminum Nitride at Very High Strain Rates
In previous work, we have used a modified compression Kolsky bar to determine the dynamic compressive strength of some ceramic materials, including aluminum nitride (AlN), at strain rates of approximately 103 s–1
