Japan Society of Civil Engineers Annual Meeting

The well-shaped method taken up here is one of the fracture test methods, in which the circumference of the strain gauge is cut into a well-shaped shape to release the stress. While this method is easy to operate, there are many situations in which it is difficult to determine it because there is no clear standard for disconnection conditions. Therefore, we decided to use FEM to examine the relationship between the cutting width and the cutting depth and the effect of the steel plate thickness to help determine the cutting conditions.
