Microstructure, residual strain, and eigenstrain analysis of dissimilar friction stir welds

Abstract:

A study of residual strains in aluminium-based dissimilar friction stir welds (FSWs) was performed by a novel approach that will be referred to as the Eigenstrain Reconstruction Method (ERM). The method is based on the theory of permanent inelastic strain (eigenstrain) as the basis for reconstructing full-field residual stress and strain states. The strain distributions evaluated by the angle-dispersive sychrotron X-ray diffraction were used to obtain the eigenstrain distributions by ERM. In ...
