| Research Abstract |
Experiments on the temperature difference for exfoliation of a three-dimensional joint have been performed to investigate crack initiation and the difference between two-and three-dimensional joints (2D and 3D) using specimens made from resin and steel. When the edge angle is less than 90 degrees, a crack initiates as the side ; therefore, the temperature difference for exfoliation of the 3D joint equals that for exfoliation of the 2D joint. When the edge angle is greater than or equal to 90 degrees, a crack initiates at the corner and the temperature difference of the 3D joint is slightly less than that of the 2D joint.
