Strains experienced by materials during friction stir welding (FSW) are important but scarce in the literature. Here we report the computed strains and strain rates during FSW of AA2524 from a three-dimensional coupled viscoplastic flow and heat transfer model. The strain rates are integrated along a streamline to estimate the accumulated strains experienced by the material. The computed strains and strain rates were in the ranges -10 to 5 and -9 to 9 s-1, respectively.
