Abstract

The purpose of this research is to investigate the interaction of two adjacent cracks under cyclic loading. A series of tests at different loads and frequencies were conducted under uniaxial constant amplitude fatigue loads on API-5L grade B steel samples. Crack growth rate of two initial semi-elliptical cracks was investigated. Marker band testing technique was employed to study the crack growth rate before and after interaction. Real time optical microscopy was used to observe crack coalescence on the specimens’ surface. Moreover, SEM analysis of the fracture surface was performed for comprehensive understanding of cracks behavior.
