<P>PROBLEM TO BE SOLVED: To provide a fatigue degree detecting strain gauge for measuring strain of a structural material and predicting fatigue breakdown locally generated in the structural material. <P>SOLUTION: The fatigue degree detecting strain gauge includes: a strain detection part 130 in which a strand 131 and an adjacent strand are connected through a folding tab 132; a folding line part 140 connected in series to the strain detection part 130 in a state that a strand 141 and an adjacent strand are connected through a folding tab 142; a bypass part 160 forming a route different from the folding line part 140 and the strain detection part 130 and configured such that one end is connected to one terminal part through the folding tab 141 of the folding line part 140 and the strain detection part 130 and other end is connected to the other terminal part; and a fatigue degree detection part 150 connected to the folding tab 142 of the folding line part 140. Respective folding tabs are connected to the bypass part 160 through the fatigue degree detection part 150, and the fatigue degree of the structural material to which the fatigue degree detecting strain gauge is stuck is detected from a degree of rupture of the fatigue degree detection part 150. <P>COPYRIGHT: (C)2013,JPO&INPIT |
