Approach to plastic deformation and strain rate in FSW process

In this work, two simple models to calculate the strain rate at which material deforms during the friction stir welding (FSW) process are proposed. In both cases, predictions are associated with operational parameters such as rotational and travel speed and tool pin radius. A first model is based on...
