Posted: Jun 22, 2010: Key puzzle in brittle-to-ductile transition in silicon resolved (Nanowerk Spotlight) Why does silicon, which usually shatters catastrophically like glass when fractured, suddenly ...

Professor K R W Wallin is a recognised expert in the field of fracture mechanics. Indeed his work has provided a major input to the currently accepted ASTM Standard on the Master Curve Method , E1921.

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 ...

Break down three essential material properties, strength, ductility, and toughness, that every engineer and designer should ...

Field observations of semi-brittle rocks show that for a range of composition, temperature and pressure, the formation of fluid-filled brittle fractures and veins accompanies localized ductile ...

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 ...
