Abstract:Typically, the crack tip opening displacement (CTOD) is used only to quantify the crack closure phenomenon. However, more information about crack tip phenomena can be extracted from the CTOD curves, which can be used for a better understanding of fatigue crack growth. The main objective here is the development of a numerical tool for the automatic analysis of CTOD plots, which can be obtained either numerically using the finite element method (FEM) or experimentally using digital image correlation (DIC).

“…The load continues to rise in this section until the peak load value is reached, at which point the material's full loading capacity is reached. As the crack mouth opening displacement continues to increase and the load begins to decrease after the peak load level, the last part begins [30].…”
