| Research Abstract |
Many bolt are used in the automobiles or bridges. Since loosing of the bolts many cause serious accidents, regular inspection is very important. In this paper, the slack inspection technique of high-tension bolt of detecting the magnetic property of changing by bolting stress was examined. The proposed of bolt slack inspection technique was investigated in 3-D stress analysis and nonlinear electromagnetic FEM(finite element method).
