Modelling failure pressure of pipeline composite repair design using finite element analysis incorporating putty’s contribution

A composite repair system which consists of Fibre Reinforced Polymer (FRP) and putty as infill material has been proven effective in repairing pipeline system as it can structurally reinforce the damaged steel pipes and potentially prevent external corrosion. However, previous studies including the...
