METHOD AND APPARATUS FOR MEASURING CRACK IN CORNER SECTION

摘要

PROBLEM TO BE SOLVED: To improve an accuracy of detecting cracks in a corner section of a structure. SOLUTION: A potential difference method for inspecting cracks in a conductive inspection object enables each contact point to be arranged so that a straight line connecting contact points where a pair of current input/output terminals contact with the inspection object and a straight line connecting contact points where a pair of potential difference measuring terminals contact with the inspection object may cross each other, tilting in an identical direction against a corner line in the corner section.
