All, I'm currently working on a ANSYS model with utilizing CZM to simulate adhesively bonded lap joints. I have some general questions about getting the model setup correctly. I've tried to attach some images to better explain my questions. I should add that the lap joints are fixed at the end of one plate, and pulled in the axial (left/right direction of the screen) at the other end. I've added my questions are bullet points to try to separate out my questions. If there's any confusion, please let me know and I'll clarify!

• When the lap joint is constructed, the adhesive is applied between the two plates. This adhesive then has a thickness (maybe 0.1mm or so). Should this thickness be utilized in the ANSYS model? I've watched multiple videos on CZM, and everyone assumes the "plates" are in direct contact (as shown in the "current model" image, below. The CZM material is then applied directly at the contacting interface.

Hello Array
Do read the help manual page Interface Delamination and Contact Debonding (ansys.com) for a better understanding assumptions, failure criteria and models used for interface delamination and contact de-bonding. Also, check out /courses/index.php/courses/fundamental-topics-in-contact/lessons/how-to-interpret-contact-penetration-lesson-3/ to understand the 2 types of contact formulations generally used.

Hi jacobengland16 ,

I am working on a similar adhesive bond and have the same issue in understanding this. Have you found the right solution/method to simulate this kind of model? Where the adhesive is a solid material sandwiched between two other solid elements. Please let me know, thanks!

Regards,

Raghu
