摘　　要：利用有限元方法研究了金属镶嵌对单搭接接头应力分布的影响。结果表明,采用镶嵌块组成混合连接接头,改变了接头的应力流线分布,镶嵌块承载,降低了搭接区中部胶层中的应力;同时使被粘物中部的应力增大,提高了接头搭接区中部的承载能力;在重要部件或承载较大等情况下使用胶接接头,建议采用金属镶嵌方式对接头增强,具有更强的承载能力和可靠性,有重要的实用价值。The finite element method（FEM） is applied to investigate the effect of metal inlay in single lap joint on the stress distribution. The results showed that the metal inlay in single lap joint changes the stress streamline and improve the bearing capacity in middle part of the lap joint. For the metal inlay, the stress in the adherend was increased. When the adhesive bonding joint was used in the important parts or to carry the big load, we can use the metal inlay to enhance the joint to lead to stronger and more reliabile joints.
