Obtaining geometric parameters, especially depth, and describing the morphological characteristics of cracks are great significance to control engineering disasters accidents caused by cracks. The electric resistance method is based on principle differences in electrical properties between soil, which could be used measure single crack depth at project sites. There exists an R min value corresp...

Electrical Resistance Tomography (ERT) offers a non-destructive evaluation (NDE) technique that takes advantage of the inherent electrical properties in carbon fiber reinforced polymer (CFRP) composites for internal damage characterization. This paper investigates a method of optimum selection of sensing configurations for delamination detection in thick cross-ply laminates using ERT. Reduction...
