Paper Title:
Effect of Restraint Condition on the Thermal Stress in the Bonded Single Lap Joint
  Abstract

The temperature field in the adhesively bonded single lap steel joint after a thermal shock (100 °C, 10s) and the influence of the restraint on the thermal stress in the joint was investigated using elasto-plastic finite element method (FEM). The results showed that the temperature in the overlap region is symmetrically distributed to the bondline after the thermal shock. Five kinds of constraints were applied in the study and it is found that the peak value of the thermal stresses were occurred at the points near the free ends of the adherend lap zone along the mid-bondline under the action of constraining the adherends in the direction of both transversal and longitudinal. The symbol of the longitudinal stress Sx and peel stress Sy is negative.
