Dear researchers,

I am currently modeling the debonding behavior of hybrid bonded FRP (HB-FRP) systems in reinforced concrete structures using Abaqus. While I have successfully used surface-based cohesive behavior for EB-FRP simulations, I am now considering whether to adopt COH3D8 cohesive elements for the HB-FRP interface to better capture the effects of mechanical anchorage.

From both research accuracy and publication acceptance standpoints, I would greatly appreciate your perspectives on the following:

• How do journals and reviewers typically evaluate the choice between surface-based cohesive contact and COH3D8 elements in structural-scale modeling?
• Is surface-based CZM generally accepted as a rigorous method for modeling interface debonding, assuming careful calibration of the traction–separation law?

Thank you very much in advance for your time and insights.
