Shock Temperature

The effect of the thermal shock temperature on the thermal stress distributed in the adhesively bonded steel single lap steel joint under a 10 s thermal shock was investigated using elasto-plastic finite element method (FEM). The results showed that both the highest temperature at the surface and the lowest one at the mid-bondline increases as the temperature of the thermal shock raised (80 C to 140 C) and all the peak values of the stresses at the mid-bondline and the zone of negative Sx in adherend increased as the temperature of the thermal shock elevated.

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.

Peak Value

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.

The effect of five constraint conditions in cooling process on the residual stress distributed in the adhesively bonded single lap steel joint under a 100°C thermal shock was investigated using the elasto-plastic finite element method (FEM). The results from the numerical simulation show that the effect of constraint model is significantly to the residual stress distributed in both mid-bondline and adherend near the interface of the adhesively bonded single lap steel joint. The constraint to the longitudinal of the adherend is much significantly to the residual stress than that of the transversal one. Comparing the action of the constraint model C and model E, the effect of the model E on the residual stress along the mid-bondline is higher than that of the model C.

Vibration Behavior

This paper deals with forced vibration behavior of adhesively bonded single-lap joint theoretically and experimentally. The finite element analysis (FEA) software was used to predict the natural frequencies and frequency response functions (FRFs) of the joint. The dynamic test software and the data acquisition hardware were used in experimental measurement of the dynamic response of the joint. It is shown that the natural frequencies of the joint from experiment are lower than those predicted using finite element analysis. It is also found that the measued FRFs are close to the predicted FRFs for the first two modes of vibration of the joint. Above the second mode of vibration, there is considerable discrepancy between the measured and predicted FRFs.

Metal Block

The effect of 4 mm long metal block bonded to the end of the overlap zone on the stress distributed in adhesively bonded single lap steel joint was investigated using elasto-plastic finite element method (FEM). The results from the numerical simulation showed that the stress is varied a little when the joints with a couple of 4 mm long metal block adhered to both ends of the over lap or with a couple of adhesive fillet. Compared to the joint without the metal block, it is advantageous of reducing the peak stress in the adhesive layer near the ends of the lap zone in adhesively bonded single lap steel joints but its effect is less than that of the joint with a couple of adhesive fillet. There is no evidential difference in the effects between the steel and aluminum block.
