Our previous study revealed three distinct fracture behaviors during tensile testing—ductile, semi-ductile and brittle—when notches ranging from 0.5 to 2.0 mm in depth were introduced to one ...

If there are too many carbon fragments, the material becomes brittle, and if there are too few, the material lacks strength. During the experiments, the team successfully created an optimally ...

CityU invents a method to convert 3D-printed polymer into a 100-times stronger, ductile hybrid carbon microlattice material Peer-Reviewed Publication City University of Hong Kong ...

When a sample is tested to fracture it may fail either by Brittle Fracture or by Ductile Fracture. In ductile fracture, considerable plastic deformation before the material fractures. The fracture ...

As predicted, the larger pillars were brittle, with the 1.8 μm pillar failing catastrophically after being compressed by just 3% of its height. However, below 500 nm, the pillars became much more ...

Projection micro stereolithography (PμSL) has emerged as a powerful three-dimensional (3D) printing technique for manufacturing polymer structures with micron-scale high resolution at high ...
