Sažetak
Multiple cracks frequently appear in actual components, such as ageing aircrafts, pressure vessels, piping systems and others. A good understanding of the behaviour of crack interaction and coalescence is essential for reliable structural integrity assessment. In this paper, the interaction of twin edge cracks in a finite plate subjected to the remote tension is investigated. The stress intensity factors (SIFs) for these cracks are calculated using two- dimensional linear finite element analysis. The results of the calculation show that crack interaction intensity and the crack interaction limit at elastic condition are influenced by crack distance ratio and crack width ratio.
