The failure mechanism of a co-cured T-joint containing an initial debond between its skin and flange is investigated in this study. A finite element model of the T-joint was developed and analyzed to investigate its failure. Virtual Crack Closure Technique (VCCT) based on fracture mechanics approach was used to investigate the onset of debond growth. A failure criteria based on interlaminar peel strength was used to predict the failure inside the Bermuda Triangle. T-joint specimens with initial debond located between flange-skin interface were fabricated through a resin infusion process. Specimens were tested by applying pull loads on the web. Numerical results showed good correlation with test data.
