Use of Cohesive Surface Element for Edge Impact

Submitted by Ozzy on

Hi all

I am wondering if anyone is aware of recent experimental tests regarding "edge impact causing delamination" as result of post impact compressive applied loads?

And the secondary question is use of Cohesive surface for impact modelling. The specific quesiton I have is how to induce the initial damage ? if impact is not modelled how can the damage area be defined?
