In present study, the stress shielding interaction is formulated as a mathematical model called stress shielding damage (SSD) model. SSD model used to define the combination and re-characterization of crack interaction from multiple cracks to single crack. Focus is given to weak crack interaction state as the crack interval exceed the length of cracks (b > a). The crack interaction factors are evaluated based on Griffith strain energy release rate and mode I SIF using J-integral analysis. For validation, the stress shielding factor parameters are compared to single edge crack SIF as a state of zero interaction in a form of crack unification limit (CUL) and crack interaction limit (CIL). 2014-03-20T09:01:53Z 2014-03-20T09:01:53Z 2013 Article Advanced Materials Research, vol. 795, 2013, pages 587-590 978-303785811-0 1022-6680 http://www.scientific.net/AMR.795.587 http://dspace.unimap.edu.my:80/dspace/handle/123456789/32929 en Trans Tech Publications |
