Radome Solutions for Ground & Ships Pshell90  (Aerospace) (OP) 11 Aug124:45Hi guys!!I'm working with PATRAN and I wanna model a sandwich beam with honeycomb core. but I don't know how to model it in PATRAN? I used COMPOSITE in material anddefined facesheet and core !!I want to know if it is a good way to define a sandwich beam ?I want to have a flutter analysis at the end !!Please help me what to do !!Thank you all in advance . ESPcomposites  (Aerospace)12 Aug1217:20There are several ways to model sandwich structure. You will not be able to capture the effects of transverse shear stiffness with that approach though. If that does notmatter to you, then your approach may be sufficient.
