    just a quick comment, this question is a little bit vague, ok?

     

    FREEZE means no relative displacement between connected parts, thus "infinite" stiffness at the interface.

    It could be used in some cases, but probably it would be better to have some finite stiffness at your interface, such as cohesive contact properties with the right stiffness and behavior of your resin calibrated by some test data. You could assign MCOHED and DMGINI/DMGEVO into a contact pair, and calibrate the cohesive material stiffness and strength.
