Numerical analysis of friction welded titanium joints
Journal Title: Journal of Achievements in Materials and Manufacturing Engineering - Year 2016, Vol 76, Issue 1
Abstract
Purpose: Friction welding is found to be a suitable candidate for joining the dissimilarmaterials. Numerical model would be helpful for proper selection of processing conditions.In the present work, a thermo-mechanical model has been developed using finite elementmethod based software.Design/methodology/approach: Friction welding process is characterized of thermomechanicalphenomenon, which is highly complex in nature. Thermo-mechanical modelis considered as highly nonlinear due to the interaction between the temperature fieldsand time dependent on the material properties. The numerical model is subject to certainassumptions and boundary conditions.Findings: The numerical investigation was carried out to predict the temperaturedistribution, heat flux, the axial shortening and stress on the friction welded titanium joints.Research limitations/implications: Leading aerospace manufacturers are exploring thejoining of titanium to titanium for aerospace applications. The approach is time saving andit is supposed to have a promising future in automotive and nuclear fields.
