Electromagnetically induced acoustic emission (EMAE) technique is a new nondestructive testing (NDT). It does nondestructive detection with the effect of dynamic electromagnetic loading to generate a stress field stimulating stress waves from the defects. When EMAE is used to detect crack in the metal sheets, the EMAE signal is easy to be disturbed by various sources of noises, and the detectability...
A new electromagnetically induced acoustic emission technique (EMAE) is presented in this paper. Due to the acoustic emission signal generated by the electromagnetically induced high-density eddy current pulse, EMAE can locate small flaws or cracks in thin-walled structures nondestructively in order to inspect specific areas without loading the whole structure. The acoustic emission (AE) signal captured...
In this paper, the finite element analysis of a recently developed electromagnetic acoustic emission (EMAE) which can be used for damage assessment of thin walled conducting structures has been reported about eddy load. Due to the local high-intensity stress field generated by the electromagnetically induced high-density current pulse, EMAE can locate small flaws or cracks in thin-walled structures...
