| Abstract(J) | 自動車車体のマルチマテリアル化のために開発された異材接合法DSWにより作製した鋼/アルミニウム合金異材接合体に対し，室温での引張せん断試験と疲労試験を行った．その結果，DSW接合体はSPR接合と同等以上の強度を持つこと，DSW接合体の疲労破壊にはフレッティング損傷が影響を与えることが明らかになった． Translation |
| Abstract(E) | Tensile shear tests and fatigue tests were performed for dissimilar joints of steels and aluminum alloys fabricated by Dimple Spot Welding (DSW), which is a novel method for dissimilar metal joining. In the tensile shear tests, two failure modes of DSW joints were observed, and the tensile shear strength was affected by the strength of base metals. In fatigue tests, failure mode was fretting fatigue, and the fatigue life was not simply determined by the strength of base metals. The both tensile shear strength and fatigue strength were higher in the DSW joint compared with the Self-Pierce Riveting joint. |
