Analysis of the initial delamination size on the mode I interlaminar fracture of carbon/epoxy composites, ICCM International Conferences on Composite Materials.http://hdl.handle.net/10400.8/12763- Full Proceedings Available Online - ICCM (International Conferences on Composite Materials) 17, 27-31 julho 2009, Edimburgo UK.This paper describes an experimental study of the initial delamination length effects on the mode I fracture toughness using DCB tests. Delamination failure was also predicted using exponential cohesive model and a quite good agreement with experimental results was obtained. Numerical predictions showed a significant influence of initial delamination length on the force-displacement curves.engcompositesfracture toughnessfinite element analysismechanical testingconference proceedings
