Hi guys, I am currently trying to solve a problem with my 3 point bending setup. I designed a hybrid composite structure with 3D elemtents as core and 2D elems as Laminate. To apply the load I have modelled a 2D Impactor which moves down and translates the forces into the laminate via contacts. (MORIENT: Norm, S2S, TRACK: finite) Everything works fine exept my results... if I view the contact forces Optistruct would give me the result as shown in the picture. Has anyone had this problem before? I have already tried using CNTSTB and defining the SRCHDIS. Changing Master and Slave or N2S and S2S did not help either. At some values the two lines of contact forces would move closer to each other but never close enough. Greetings from Germany Lars
Hi, I have some questions I was hoping someone could answer. I am trying to model a sandwhich structure with carbon fibre skins and aluminium honeycomb core and then perform a 3 point bending test in the software if possible. 1. Could someone please explain what the reason is for selecting PCOMPP, PSOLID etc, what are the reasons for choosing one of them over another? 2. Which compersite property: PCOMPP, PSOLID, PSHELL, etc, do I need to select for the task I want to achieve (3-point bending simulation)? 3. Another question relates to my understanding of the MAT 8 card....would I be correct in saying that as MAT8 only asks for the in-plane properties, it would not be possible to get proper results for a 3-point bending test in the software? (Or does the software still work this out?) 4. Would I need to use the MAT9 card for what I am trying to do and in that case what composite property do I select, PCOMPP, PSOLID, PSHELL, etc? 4. If I select for example PCOMPP for the honeycomb properties, do I have to select PCOMPP for the carbon fibre skin properties? Regards
