Popis: Delamination onset and propagation of an initial radial disbond in the noodle region of a T-section has been studied in detail. Pull-out loading coupled with residual stresses due to curing has been accounted for in the analysis. A rigorous finite element analysis in conjunction with virtual crack closure technique has been adopted to model delamination onset and growth. Thickness variation due to increasing number of plies and tool geometry variation has been quantified. Residual stresses due to curing are found to be very detrimental to the load-carrying capability of the T-joint.
