When the elastic modulus is high, stress and strain are mainly concentrated at edge of the overlap region, while those in weld spot zone are relatively even; when the elastic modulus is low, stresses in the adhesive layer are small while stresses are concentrated to a certain extent at edge of the weld spot.

分析发现，胶粘剂弹性模量对接头中应力应变分布的趋势有明显影响，胶粘剂弹性模量高时，搭接区边缘附近区域应力应变高，焊点区应力应变值相对较小；弹性模量低时，焊点边缘处存在一定的应力集中，胶层中应力较小。
