SubscriberHi,Â
I am using shell elements for an I section and applying blast loading on its weak axis. I couldnt able to establish proper contact between flange and web. Any suggestions which contact is more suitable! I tried merging nodes but couldnt achieve good results

Ansys EmployeeI suggest that flange and web share nodes at their juncture even though it means there's some slight overlap of material at that juncture.   *CONTACT_AUTOMATIC_SINGLE_SURFACE would only be needed if deformation were extremely large, such as would occur if the section buckled.
If that doesn't help, provide an image that illustrates the bad behavior.
