Further discussion on newly developed failure criteria for fibrous composites
MetadataShow full item record
Recently, a new set of failure criteria was proposed by the authors (Kwon and Darcy in Multiscale Multidiscip Model Exp Des 1(1):3–17, 2018), which was based on a multiscale modeling technique. The failure criteria used stress and strain values at the constituent material levels. This paper presented the failure criteria in terms of a general framework for any reinforced composite material. The paper also discussed progressive failure modeling of laminated composite structures as local materials fail based on the failure criteria until the ultimate failure of the structure. To further validate the proposed failure modeling technique, experiments were conducted to obtain the failure data of filament-wound composite cylinders subjected to internal pressure loading. The test data were also compared to the numerical predictions.
