Electromagnetic pulsed thermography for natural cracks inspection. [PDF]

open access: yesSci Rep, 2017
AbstractEmerging integrated sensing and monitoring of material degradation and cracks are increasingly required for characterizing the structural integrity and safety of infrastructure. However, most conventional nondestructive evaluation (NDE) methods are based on single modality sensing which is not adequate to evaluate structural integrity and ...
