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.

Plastic collapse loads Pc and CTODs of a cracked Circular Hollow Section (CHS) T-joint
, 2012 The FailureAssessment Diagram (FAD) is an accepted approach in assessing the structural safety and integrity of any cracked tubular joint. In order to extend its application to a more complex geometry of any cracked Circular Hollow Section (CHS) tubular T-joint, there are three major challenges needed to be overcome; firstly there is a need to validate
