What is Dynamic Analysis of a Beam with Additional Auxiliary Mass Spatial Via Spectral Element Method about?

This paper aims to propose a new spectral element with additional mass. Methodologies for structural health monitoring are used to include additional auxiliary mass in the structure to change of natural frequencies. Therefore, the additional auxiliary mass can enhance the effects of discontinuities in the structural dynamics response, which could improve the identification and location of the discontinuities. The proposed approach deals with the wave propagation in structures regarding the spectral analysis method. The change in the natural frequencies due the mass is examined by comparing the differences between the dynamic responses of the beam with and without additional auxiliary mass. Similar analyses also performed with the Galerkin assumed modes technique to validate the new spectral element. The proposed technique is validated with numerical simulation and then compared to experimental data. Keywords Spectral element method • Auxiliary mass spatial probing • Galerkin assumed modes technique.
