研究了在胶瘤中嵌入三角形金属楔块对单搭接接头强度和应力分布的影响,结果表明,金属楔块能显著提高接头的强度。但随三角形锲块入射角度的增大,接头强度提高幅度逐渐降低。有限元数值分析的结果表明,三角形金属楔块使端部应力峰值和平均应力均大大降低,剥离应力降低明显。
The effect of embedding triangular metal wedges on the strength and stress distribution of single lap joints was studied. The results show that the metal wedge can significantly improve the joint strength. However, as the angle of incidence of the triangular wedges increases, the strength of the joint decreases gradually. The results of finite element analysis show that the triangular metal wedge reduces the peak stress and the average stress greatly, and the peel stress decreases obviously.
