Abstract
The effect of the notch depth on the impact properties of the adhesively bonded steel butt joint under the Charpy impact test is studied using both the finite element method (FEM) and experimental method. The results obtained from numerical simulation showed that the value of the peak stressSeqvincreased first and then decreased evidently when the notch depth increased from 2 mm to 8 mm. Comparing the results with that from Izod impact test, it is found that the response time retarded about 0.02 ms and the peak value of the stressSeqvdecreased evidently under the Charpy impact test. The results from the experiments showed that the effect of notch depth on the impact energy absorbed by unit area of joint is as same as that from the Izod impact test.
