Problem in capturing contact force-time responses of FRP wrapped steel tubes under drop mass impact

Problem in capturing contact force-time responses of FRP wrapped steel tubes under drop mass impact

(OP)
I am trying to validate my drop mass impact test results with ABAQUS/Explicit impact simulation. The specimens were bare and CFRP wrapped CHS steel tubes. I got good agreement in case of bare column. However, in CFRP wrapped columns I'm facing problems in capturing contact force-time response of impact tests. The displacement time curve of CFRP wrapped tube reasonably agreed with tests considering the complexity of the model. Please find here mid span displacement and contact force time history comparisons as attached picture with this thread. I have used continuum shell elements to model CFRP and cohesive elements to model adhesive between the layers.

I'm wondering whether continuum shell is capable of capturing the contact force response such dynamic problems or I have to used 3D solid elements by using VUMAT subroutine. I will appreciate if anyone can provide me with any help on this issue.

Thanks a lot.
