| Abstract Scope |
Friction stir scribe technique (FSST) is becoming a popular method to join dissimilar materials in lap configuration. The mechanical properties and performance of a FSST joint are governed by its underlying interfacial and microstructural characteristics, which in turn are determined by the process parameters. In this work, a finite element method based computational approach with experimental support was developed to identify the optimal interfacial characteristics that lead to desirable mechanical performance of a FSST joint. The accuracy of the computational model was verified by experimental observations. A sensitivity analysis was conducted to study the variation in the mechanical response and failure mode of the joint with respect to the interfacial characteristics. Results indicate that interfacial characteristics can have a significant impact on the joint strength and ductility. |
