Damage Detection of Pipes Based on PVDF


Article Preview

To detect the pipes, this paper introduces the electro-mechanical impedance (EMI) method into online monitoring for the pipes. The pipes model with a Polyvinylidene Fluoride (PVDF) bonded on it is built. The finite element method is employed to analyze the electro-mechanical impedance of the PVDF, the conductance curves of PVDF are obtained with different damaging phase of the pipes, the root-mean-square deviation (RMSD) is used to assess the damage extent. The result indicates that EMI as a new detection method is effective in identifying the existence and severity of cracks in pipes. As the corrosion area increases, the difference of conductance curves becomes more obvious and the RMSD becomes larger.
