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
Hi All Trying to run an Optistruct analysis to see how two layers of different materials will displace when experiencing a thermal load. In my case I have chosen points along a lattic where the temperature would be 80degC. But when running my model in Optistruct and in trying to view the results, the model cannot show a viable solution or a solution that makes sense, in fact, I have not setup the pre processing properly (it seems) which has lead to a model with massive deformation. Also I am unable to view the contours. The attached picture shows circled areas (red) where I have made equivalence nodes, there is an expected connection at these points (not defined). Hoping that anyone could give advice or guidance! Phil Busbar Copper Lattice Model 2D.fem Busbar Copper Lattice Model 2D.mvw
