Abstract:In this paper, the propagation of tunnelling cracks in composite laminates subjected to uniaxial force-controlled and strain-controlled cyclic loading is analysed considering both interacting and non-interacting cracking scenarios. Glass fibre reinforced polymer laminates with [Formula: see text] layup are used in the analysis. For non-interacting cracks, a strain-controlled test under a single strain value is found to be sufficient to produce the slope of the Paris-Erdogan law type curve relating the crack fr… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
