چکیده
Non-Destructive testing is useful in rail, pipeline and aerospace industries for maintenance of equipment, such as thickness measurements, corrosion and defect detection in materials. In this work a finite element analysis of an Electromagnetic acoustic transducer is presented. EMAT is an emerging technology that provides a non contact process of testing materials compared to ultrasonic sensors that requires a coupling medium. The acoustic properties of the material are investigated, which involves the coupling of several physical parameters, which includes mechanical and electromagnetic properties. An investigation of defect detection in an aluminum and steel plate material is conducted. Results obtained shows the model is capable of detecting defects in aluminium and steel plates using an Electromagnetic acoustic transducer.

Multi-Mode Electromagnetic Ultrasonic Lamb Wave Tomography Imaging for Variable-Depth Defects in Metal Plates
This paper proposes a new cross-hole tomography imaging (CTI) method for variable-depth defects in metal plates based on multi-mode electromagnetic ultrasonic Lamb waves (LWs). The dispersion characteristics determine that different modes of LWs are sensitive to different thicknesses of metal plates. In this work, the sensitivities to thickness variation of A0- and S0-mode LWs are theoretically...

Consider a piezoelectric transducer that is attached to the back of a plate-like structure, such as is the case for guided wave structural health monitoring. This transducer may be excited to produce guided waves that propagate outward from the source through the structure. These waves interact with impedance discontinuities in the structure at defects, bond lines, plate boundaries, and other g...
