On the exceptional damage-tolerance of gradient metallic materials [PDF]
, 2020 An experimental study is described on the fracture toughness and micro-mechanisms associated with the initiation and propagation of cracks in metallic nickel containing marked gradients in grain size, ranging from ∼30 nm to ∼4 μm.

High-resolution 3D weld toe stress analysis and ACPD method for weld toe fatigue crack initiation [PDF]
, 2019 Weld toe fatigue crack initiation is highly dependent on the local weld toe stress-concentrating geometry including any inherent flaws. These flaws are responsible for premature fatigue crack initiation (FCI) and must be minimised to maximise the fatigue

Crack path in aeronautical titanium alloy under ultrasonic torsion loading
Fracture and Structural Integrity, 2015 This paper discusses features of fatigue crack initiation and growth in aeronautical VT3-1 titanium alloy under pure torsion loading in gigacycle regime. Two materials: extruded and forged VT3-1 titanium alloys were studied.

Cracking Mode Analysis of Crack Initiation in Rocks under Uniaxial Compression
Advances in Civil Engineering, 2019 Crack initiation is related to the behavior of the preexisting microcracks within a rock specimen, which suggests the specimen starts to fail. The determination of crack initiation stress is important for identifying the elastic stage and related ...

A Framework for Predicting Fatigue Crack Initiation Life in Pipelines with Girth Welds
Journal of Marine Science and EngineeringCurrent studies on fatigue crack initiation in pipelines remain relatively limited. Existing frameworks are confronted with issues including difficulties in crack monitoring and limited consideration of intragranular short-crack propagation.

Near-threshold fatigue crack growth in bulk metallic glass composites [PDF]
, 2009 A major drawback in using bulk metallic glasses (BMGs) as structural materials is their extremely poor fatigue performance. One way to alleviate this problem is through the composite route, in which second phases are introduced into the glass to arrest ...
