In order to better understand the usefulness of single lap shear testing for the characterization of resistance welded thermoplastic composite joints, finite element method (FEM) and digital image correlation measurements (DIC) were combined to investigate the strain distributions of the joints during testing. Glass fibre reinforced Polyphenylene Sulfide (GF/PPS) was resistance welded in aid of a metal mesh. Shear and peel strain distributions were investigated at the joint overlap area. The effect of the resin fillet and metal mesh on the strain distributions and apparent shear strengths was investigated. A comparison between resistance welded and adhesively bonded GF/PPS joints was performed
