Journal ArticleDOI
Measurement of resistance curves in the longitudinal failure of composites using digital image correlation
TL;DR: In this paper, the authors presented a new methodology to measure the crack resistance curves associated with fiberdominated failure modes in polymer-matrix composites, which is based on the identification of the crack tip location using Digital Image Correlation and the calculation of the J-integral directly from the test data using a simple expression derived for cross-ply composite laminates.
Journal ArticleDOI
A finite fracture mechanics model for the prediction of the open-hole strength of composite laminates
TL;DR: In this article, a new model based on finite fracture mechanics is proposed to predict the open-hole tensile strength of composite laminates and failure is predicted when both stress-based and energy-based criteria are satisfied.
Journal ArticleDOI
Three-dimensional failure criteria for fiber-reinforced laminates
TL;DR: In this article, a new fully three-dimensional failure criteria for polymer composites reinforced by unidirectional fibers is proposed, where the effect of ply thickness on the material strength is accounted for.
Journal ArticleDOI
Micro-mechanical analysis of the in situ effect in polymer composite laminates
TL;DR: In this article, a micro-mechanical finite element model of a composite sublaminate is proposed to study the mechanical response of ultra-thin plies, consisting of a representative volume element of a 90 ° thin lamina in-between two homogenised ± θ ° plies.
