The adhesively bonding technology has been widely used. The delamination and cracking failure is main failure form of adhesive structure. This paper used the VUMAT subroutine and bonding structure models based on the bond behavior of the contact interface to establish the adhesive structure of five layers. The different crack processes of butt joint and lap joint were simulated. The results showed that the adhesive structure failures was consistent with the predicted under the bonding strength of interface ...
