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 ...

Fracture of materials has been classified into two types: brittle and ductile fracture. Brittle fracture takes place just after a Hookean regime. Ductile fracture, on the other hand, accompanies a ...

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 ...

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 ...

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.
