Notes:
The stress distributed in the mid-bondline of the joints made of aluminium alloy and anepoxy adhesive was determined with the ANSYS software. The results from the FEA showed thatthe values of the peak stresses of the all the stress components (including the longitudinal stress Sx,the peel stress Sy, the shear stress Sxy, the 1st principal stress S1 and the von Mises equivalent stressSeqv) distributed in the mid-bondline are changed a little as the notch distance L was increased whilethe notch depth d was not great than 0.6mm. But the evidently changes occurred when the notchdepth d was great than 0.9 mm for the stress Sx, Sy and S1 distributed in both the mid-bondline andthe interface of the lap zone. When taken the stress distributed in the middle part of the lap zone intoaccount, the peak stress at the point in the mid-bondline corresponding to the edge of the notchdecreased firstly and then increased again as the notch distance L was increased from 0 mm to 8 mm.The proper geometry of the notch in the specimen was chosen by finite element analysis
