However, FEA is only an approximate method. In order to evaluate the actual mechanical stress on the surface of fiber reinforced plastics (FRP) rod during crimping and tensile process. stress testing utilizing foil gauges were performed on the crimped insulator ends subjected to compression or axial tensile loads. Variations of axial strain of rod surface in the compression procedure for various crimping conditions on mechanical strength were tested. The tested axial stress distribution along the axial FRP rod under various tensile loads was given, and the influence of different crimping conditions on stress concentration of FRP rod was discussed. In addition, experimental testing results have been compared with the numerical data obtained by FEA method.
