Stresses in spotwelded joints, adhesive bonded joints and weldbonded joints are calculated and studied using the computational model established.
计算并对比研究了胶焊和点焊、胶焊和胶接接头中的应力。
2
The first peak load is lower slightly than the fracture load of adhesive bonded joints, and the second peak load is almost the same as the fracture load of the spotwelded joints.
曲线上第一载荷峰值略低于单纯胶接接头的断裂载荷，第二载荷峰值与单纯电阻点焊接头的强度基本一致。

Based on the hardness analyses of actual spotwelded joints, a computational model that consists of nugget, HAZ and base metal is established for the single point spotwelded lap joints.
