Description
With regard to the development of hybrid friction stir welding-adhesive bonding (FSW-AB) for the fabrication of lap joints, a mesh free coupled thermomechanical simulation of the FSW-AB process was undertaken using the SPHriction-3D code and the numerical results were compared with experimental results. Based on a Lagrangian frame of reference, continuum mechanics equations describing the physics of the FSW-AB process were cast into an amenable set of algebraic equations using a weak-strong form approach called smoothed particle hydrodynamics. A thermal degradation model of the adhesive in the FSW-AB joint was formulated from Fourier transform infrared spectroscopy analysis of Teroson 5089 epoxy based adhesive at temperatures in the range of room temperature to 210 deg.C. The numerical simulation framework was used to determine process parameters and joint design to facilitate minimum adhesive degradation
