Description
An integrated modelling approach, incorporating coupled process, material response and material performance models, was developed and implemented for use in friction stir welding (FSW) of aerospace structures. The process model employed was a dynamic coupled fluid flow thermal model capable of predicting weld heat generation and temperature from material properties, tool and plate dimensions, and process parameters. The material response model comprised microstructural and residual stress sub-models (elastoplastic modelling using ABAQUS finite element analysis). The material performance model targeted mechanical properties, corrosion behaviour and fatigue performance. Hardness profiles and temperature maps are reported for aluminium alloy FSW welds.
