Different Failure Styles for Aluminum-Alloy Strip with Two Holes under Cyclic Tensile Loading

Abstract:

Article Preview

This paper reports seven failure styles found in our experimental investigation for the failure between two neighbor holes located at different angle in an Aluminum-Alloy strip under cycle tensile loadings. In some cases, unlike expected, the initial fatigue crack is found not to nucleate at the center region between the two holes, where the stress concentration is larger than other region. In fact, the initial fatigue crack always nucleates at the outside rim of two holes far apart from the center region. The coalescence between the two holes always occurs far after the initial fatigue crack nucleation.
