이종재료의 결합방법에 따른 모자형 단면부재의 충돌실험

To apply the new joining methods to automotive joints, firstly, joint strength of new joining methods was tested by basic mechanical test methods which are tension, torsion, bending test, etc. And then characteristics of crushing of simple structures joined by new joining methods were evaluated by the crush test. In this paper, double hat-shaped members which consist of dissimilar materials with adhesively bonded, self-piercing riveted, and riv-bonded were tested on axial crush load. Fracture shape of joint part and absorbed energy of each joining method were concerned .
