Forecast of the fatigue crack initiation site of commercially pure Titanium miniature specimens with local surface topography data [PDF]
MATEC Web of Conferences, 2020 Surfaces of technical components rarely appear in perfectly smooth condition. During fatigue loading, stress concentrations at surface asperities cause localized plastic deformation that can lead to crack initiation.

Leaf modification delays panicle initiation and anthesis in grain sorghum [PDF]
, 2001 Water stress at anthesis is the major cause of yield reduction or crop failure in grain sorghum [Sorghum bicolor (L.) Moench] in central Queensland. Rainfall is difficult to predict and it is impractical to substantially alter the timing and amount of ...

Thermomechanical modeling on the crack initiation of NiTi shape memory alloy [PDF]
Computer Methods in Materials Science, 2022 The fracture of shape memory alloys is distinct from that of conventional metals, owing to the coexistence and interaction of multiple special features such as martensitic transformation, dislocation-induced plasticity, thermomechanical coupling and ...

Statistical study on the effects of heterogeneous deformation and grain boundary character on hydrogen-induced crack initiation and propagation in twining-induced plasticity steels [PDF]
, 2021 The initiation and propagation of hydrogen-induced cracks (HICs) in twining-induced plasticity (TWIP) steel were quantificationally explored based on the HIC statistics at a macro level and a micro level by slow strain rate tensile (SSRT) with in-situ ...
