Scaling of Crack Surfaces and Implications on Fracture Mechanics

, 2000
The scaling laws describing the roughness development of crack surfaces are incorporated into the Griffith criterion. We show that, in the case of a Family-Vicsek scaling, the energy balance leads to a purely elastic brittle behavior. On the contrary, it

Light and electron microscopy of microstructure and fractography of an ultrahigh-strength martensitic steel [PDF]

, 2014
Microstructure, tensile properties and fractography have been examined in the oil-quenched samples of a low-alloy ultrahigh strength 4340 steel. Intergranular fracture was revealed to locate at the fracture origin.
