Abstract

Based on the material's inherent functional properties, the work established a method of detecting the depths of double cracks for conductive concrete by use of a simplified electrical model. Kirchhoff's law is used to construct a computation method for the boundary potential response under current excitation, and an inversion method for double cracks length detection is established. In order to verify this method, the potential response data of double-crack damage in conductive concrete specimens at various locations and sizes were obtained using ANSYS Parametric Design Language (APDL) command flow. Good agreement was found in the results of theoretical calculations and numerical simulations.
