Effect of Shock Time on the Thermal Stress in the Single Lap Joint
The effect of the thermal shock time on the thermal stress distributed in the adhesively bonded steel single lap steel joint under a 100 C thermal shock was investigated using elasto-plastic finite element method (FEM). The results showed that the temperature is symmetrically distributed to the bondline in the overlap region and the lowest one at the mid-bondline increases as the time of the thermal shock elongated (4 s to 40 s). And all the peak values of the stresses at the mid-bondline and the zone of negative Sx in adherend decreased as the time of the thermal shock elongated.
