Abstract

In this work the fiber reinforced polymer FRP patch is utilized to restore damaged metallic pipe with outer part through circumferential crack. A circumferential patch was employed to cover the full surface of the pipe at the cracked area. Linear elastic fracture mechanics LEFM scheme and finite element method ware used to evaluate the stress intensity factor (SIF) and the crack opening displacement (COD) as characterizing parameters along the surface crack profile. ANSYS package was utilized in this study and 3D-20 nodes solid element was adopted. Two loading conditions were investigated, that is, axial load and bending load. It was found that COD and hence the SIF reduced considerably in the vicinity of the crack tip using the stiffened technique.
