Abstract:
Structural stress solutions for flow drill screw (FDS) joints in lap-shear specimens of aluminum 6082-T6 sheets with and without clearance hole (without and with gap) are investigated. Analytical structural stress solutions at the critical locations of FDS joints based on the analytical solutions for a rigid inclusion in a thin plate under various loading conditions are first obtained. Finite element analyses are then conducted to verify the analytical solutions. The fatigue life estimations of the FDS joints in lap-shear specimens with and without clearance hole (without and with gap) based on the structural stress solutions are in agreement with those of the experimental results.
