On the Stress Responses in Butt Joint under Izod Impact Testing

Article Preview

Abstract:

The response of the equivalent stress (Seqv) in adhesively bonded steel butt joint and the adhesive bondline during Izod impact test is studied using the finite element method (FEM) software ANSYS. The results obtained show that the highest value of the stress Seqv almost higher than the yield strength of the adherend reached within about 0.1 ms. The contour diagram of the stress Seqv is symmetrical to the axis along the half height of the specimen both in whole adhesively bonded steel butt joint and the adhesive layer. The peak value of the Seqv in adhesive increases first and then decreased when the action of the impact was over. The stress Seqv in both ends of the specimen kept to a relative lower value during impact procedure.
