Abstract
The present disclosure describes methods of inspecting polymeric material that includes one or more elongated ferrous reinforcements. The method includes applying a magnetic field to any one or more reinforcements. The method further includes positioning an array of magnetic flux sensors near the one or more reinforcements, and detecting the presence of magnetic flux leakage along any of the one or more reinforcements. It is then determined whether the magnetic flux leakage occurs at a damaged location along the one or more reinforcements or at a reinforcement joint.
