Permanent indentation characterization for low-velocity impact modelling using three-point bending test [PDF]
This paper deals with the origin of permanent indentation in composite laminates subjected to low-velocity impact. The three-point bending test is used to exhibit a non-closure of matrix crack which is assumed as a cause of permanent indentation ...

Testing 3D Printed Carbon Fiber Durability for Next‐Gen Fusion Reactors via Proton Irradiation
Schematic of proton irradiation effects on carbon fiber samples evaluated via nanoindentation and Raman spectroscopy. ABSTRACT Carbon fiber‐reinforced composites are promising candidates for plasma‐facing components (PFCs) in next‐generation fusion reactors due to their high strength‐to‐weight ratio, thermal stability, and radiation resistance. However,

Study on Size Effect in Indentation Tests
The depth dependence of the indentation hardness, i.e., the indentation size effect (ISE), was manifested as an increase or decrease in hardness when penetration depth decreases, which was observed by previous experiments.

From 2009 to 2025, we have recorded the physicochemical parameters of the water and the hydrological regimes at localities hosting Astyanax mexicanus cavefish and surface fish populations in Mexico. Sampling 13 caves and 30 surface stations revealed strong signatures of the two macrohabitats, but also significant differences in specific water ...

Theoretical and experimental researches of size effect in micro-indentation test
Micro-indentation tests at scales on the order of sub-micron have shown that the measured hardness increases strongly with the indent depth or indent size decreasing, which is frequently referred to as the size effect.

Nanoindentation Properties of Ti‐yAl‐Mo Fabricated via Plasma Activated Sintering
Ti‐yAl‐1Mo alloys were synthesised via plasma‐activated sintering, achieving near‐full densification and predominantly α‐Ti microstructures. Nanoindentation revealed strong composition‐dependent improvements, with Ti‐7Al‐1Mo showing more than double the hardness of commercially pure titanium.

Introducing novel and sustainable feed ingredients is essential to improve the environmental impact of fish aquaculture. Some species of seaweed, such as the green alga sea lettuce (Ulva fenestrata), constitute a promising novel ingredient due to their suitable amino acid profile and favourable growth traits. However, the effects of farmed Ulva in feed

Indentation Size Effect on the Hardness of Silicon Carbide Ceramics [PDF]
The Vickers hardness of CVD SiC ceramics is determined as a function of the indentation load. Vickers hardness pyramid-shaped sharp diamond indenter with angle between opposite faces at an angle of 136° was used to apply five indentation loads of 4.91; 9.
