Hello Feiyu Shi,
The command CZMESH is usually used for this application to add a Cohesive Zone Material Model in the system.

CZMESH (ansys.com)

More details on the element can be found as follows-
INTER202 (ansys.com)
13.202. INTER202 - 2D 4-Node Cohesive (ansys.com)

Here are some of the examples which use INTER202, which might serve as a good reference in resolving the issue.
Case Description- VM248 (ansys.com)

Hope this helps!
