Ductile fracture in metals is a progressive process driven by microscopic void nucleation, growth and eventual coalescence under plastic deformation. The local stress state, characterised by stress ...

The fracture surface associated with ductile fracture is shown in the photograph for a low carbon steel tested at high temperature. The top photograph shows the fracture surface at the center region ...

The Batelle two-curve method of fracture-arrest prediction for X70 and X80 high toughness steels requires correction factors based on the steel’s grade and toughness level. Data illustrate the ...

Researchers have demonstrated that rotary ultrasonic machining can drill high-quality holes in single-crystal silicon by modifying the material ...
