Hi There ,
I'm a newbie to Femap , since i've been in a project that depends on making sandwich composites and analyzing them , i've heared that Femap is one of the best for doing this job but the problem is i just have a plate of (0.5x0.5 m^2) of Foam core sandwich material and Carbon Epoxy Facesheets . I want to model the material to be analyzed , i've tried to make solid laminate element but always the result seems to have a problem , so does any one have thoughts for applying the right element type for the plate material and how ? ,
Thanks in Advance
If you can use a shell element instead of a solid, use the API script under the Custom Tools > Honeycomb PSHELL > HoneyComb PShell Property command. This will prompt you for the data needed to create a PSHELL property using the NASA FEMCI guidelines.
See Section 9 of the api\CustomTools.pdf file.
I hope its OK to resurrect this thread. I have a follow up question about the NASA FEMCI Honeycomb PSHELL API. Can this API be used for composite honeycomb laminates as well? If I have a face sheet lay up of (0/+45/-45/90) with a total facesheet thickness of 0.0216", how do I "represent" the facesheet material which captures the layup? I guess one option would be to create a PCOMP of the above lay up and use Femap's laminate property calculator to figure out laminate's engineering properties i.e. Ex, Ey etc and create a new isotropic material (MAT1) entry and refer it to the API. But if Ex & Ey are different, which one to choose for MAT1 entry? I guess, I would go with the higher one since the stiffer the material, greater load it attracts and thus may be more realistic representation of the facesheet/laminate?
