Based on a non-destructive inspection using X-ray computed tomography, a probabilistic scheme for integrity assessment is implemented, considering the effect of typical, inherently manufacturing induced defects which are statistically distributed through the material. For the integrity assessment itself, a customized damage mechanics material model is developed and implemented as user-defined material model into a commercial finite element code. The model is validated against an experimental data base on coupon and full-scale structural tests.enCFRP vesselsfilament windingmaterial modeleffects-of-defectsintegrity assessmentconference paper
