Evaluation of Tensile Failure Progress in FRP Using AE Tomography and Digital Image Correlation

Recently some applications of Fiber Reinforced Plastics (FRP) in actual structures have been reported. However progresses of failures in FRP are still not well known. Additionally the evaluation/inspection methods against defects of FRP in actual structures are of high demand. In this study failure progresses in a FRP sampled from an actual bridge were evaluated using Acoustic Emission Tomography (AET) and Digital Image Correlation (DIC) during a tensile test considering the applicability of these methods as future inspection methods in actual structures.
