Effect of Shock Time on the Thermal Stress in the Single Lap Joint

Article Preview

Abstract:

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.
