A model to quantify fatigue crack growth by cyclic damage accumulation calculated by strip-yield procedures

Samuel Elias Ferreira, Jaime Tupiassú Pinho de Castro, Marco Antonio Meggiolaro

Elber's hypothesis that DeltaKeff can be assumed as the driving force for fatigue crack growth (FCG) is the basis for strip-yield models widely used to predict fatigue lives under variable amplitude loads, although it does not explain all…

Using DIC techniques to measure strain ranges inside the cyclic plastic zone ahead of a fatigue crack tip

Giancarlo luis Gómez Gonzáles, Julián Andrés Ortiz González, Jaime Tupiassú Pinho de Castro, José Luiz de França Freire

A stereo microscope coupled to a 3-D Digital Image Correlation system is used to measure strain ranges on the cyclic plastic zone ahead of a fatigue crack-tip. First, a very refined speckle pattern is applied on the surface of a…
