Detection Of The Defects In Cylindrical Pipes: Application To The Wave Finite Element Method |
Abstract | ||
|---|---|---|
In this paper, we present an inexpensive and robust tool for the vibratory monitoring of cylindrical pipes. The tool will be based on the analysis of the anomalies which affect the elastic waves travelling in the pipe. We develop a numerical approach to study the guided elastic wave propagation in tubular structures. Wave finite element method (WFEM) based on the characterisation of the elastic waves is introduced to investigate the dispersion and wave scattering in pipes. Dynamic reduction technique is employed to improve the computational efficiency. Through WFEM and using a modal decomposition, we develop the dynamical behaviour of the pipe. We study the detection of some defects which affect the junction between two adjacent pipes. The question of the mode sensitivity to the defect's detection is considered. |
