PROBLEM TO BE SOLVED: To provide a method for acquiring crack opening behavior enabling the crack opening behavior to be detected with high accuracy.;SOLUTION: The method for acquiring crack opening behavior includes: a first mounting step of providing a first strain gauge 3 in an area including a center in an extension direction of a crack 2 on a surface of a test object 1 so as to be across the crack 2 in a direction crossing the extension direction; a second mounting step of providing a second strain gauge 4 in a position spaced from the crack on the surface of the text object 1; an output acquisition step of acquiring outputs of the first strain gauge 3 and the second strain gauge 4, which are output when a load is applied to the test object 1; and a difference calculation step of calculating a difference between the output of the first strain gauge 3 and the output of the second strain gauge 4.;COPYRIGHT: (C)2015,JPO&INPIT
