Object Grating Method Application in Strain Determination on CTOD Tests
Strain, 2006 Abstract: Standard fracture toughness tests require standard specimens with the presumption that mechanical properties are uniform in the crack growth direction. Standards for crack tip opening displacement (CTOD) fracture tests prescribe remote crack mouth opening displacement, which can lead to inadequate results in the case of heterogeneous ...

Computing the stress intensity factor range for fatigue crack growth testing at 20 kHz
Engineering Reports, Volume 6, Issue 6, June 2024.A comparative study on the computation of the SIF at 20 kHz load frequency. Results from different simulation procedures are presented and discussed. Abstract Inertia and damping influence the values of the stress intensity factors (SIFs) at high‐frequency loading and they must be included in computations.
