Machine Vision-Based Fatigue Crack Propagation System. [PDF]
Sensors (Basel), 2022 This paper introduces a machine vision-based system promising low-cost solution for detecting a fatigue crack propagation caused by alternating mechanical stresses. The fatigue crack in technical components usually starts on surfaces at stress concentration points.

Analysis of the influence of defects on fatigue resistance of metallic components [PDF]
MATEC Web of Conferences, 2014 The influence of defect on fatigue resistance of components is carried out by using a propagation threshold approach to estimate the high cycle fatigue resistance of components from data of intrinsic properties of the material.

The influence of crack tip shielding on fatigue crack propagation [PDF]
Fracture and Structural Integrity, 2017 The fatigue crack propagation is one of the major problems and of the real concern in the evaluation of the structural integrity of components. This is due to the fact that once a fatigue crack has been detected it is also known its effect on the ...
