The functions of stitch thread in stitched composite single-lap joints are investigated by experimental measurement and finite element (FE) simulation. Through microscopic observations, it is found that stitches severely destroyed the microstructures of laminated composites, which should have impact on the mechanical behaviors of the composite around the stitches. Digital image correlation (DIC) technique is used to measure the strain fields near the stitches when the specimens are under tensile loading. The experimental results reveal the degeneration of the mechanical properties of the composite near the stitch threads. In FE analysis, the virtual crack closure technique (VCCT) is used to analyze the effect of the stitches on the strain energy release rate (SERR) for a delamination progressing along the interface between the adherends. The FE results indicate that stitches can effectively restrain the extension of the delamination between the two adherends.
