Abstract: In this study, a smartphone is idealized for use in the structural health monitoring (SHM) of infrastructures using magnetic field intensity detection. Experimental and numerical studies are performed on a steel plate with different damage states. The damages states are cracks and holes. The damages are in various combinations to determ ine the effectiveness of the proposed method. The magnets' magnetic field intensity variations are detected using the smartphone, with numerical simulations showing good agreements with the experimental results. The proposed smartphone-based SHM approach is considered a cost-effective and user-friendly platform for damage detection of coastal and offshore infrastructures.
