MODELLING AND DETECTING OF ADDITIONAL MASS IN PIPES BY THE SPECTRAL ELEMENT METHOD
A spectral element is developed to study the guided wave propagation along a pipe. A damage model characterizing additional mass is incorporated into the formulation of the spectral finite element that is used for damage detection of pipes. Experimental tests are carried out on a steel pipe with embedded piezoelectric elements to check the performance of the proposed model and algorithm. Parametric studies are performed to evaluate the effect of different additional masses on wave propagation in pipes. Numerical simulations and experimental results show that the method is effective to model wave propagation along the steel pipe and promising to detect the location and magnitude of the additional mass on the pipe.
