Abstract: In this study the finite element method is used to analyse the performances of bonded composite wrap repair in cracked pipelines. Parametric analysis was performed in order to highlight the effects of the geometrical properties on the repair efficiency. The obtained results show that the optimization of the geometric properties of the wrap is still required to best improve the quality of repair.
