the laminator

[Gionata]

Thank you very much wave, all clear. I solved every doubt.
I realized... that this is just the beginning!

I have another doubt.
if with laminator pull out the apparent modules of a laminate we hypothesize of 5mm.
I put these data in a fem where I have my model with 5mm thickness.
at this point I have the doubt that the fem multiply for 5 (the 5mm thick) the values inserted.
Is it possible? or are they off the road?

I doubt you're missing basic concepts.

elastic modules, as well as tensions, are expressed in n/mm^2
means that they do not depend on the thicknesses, but only on the material, as they are precisely loads divided by the area that carry them.

you must correctly define materials, geometries.
If 3d models, as far as the material is concerned, elastic modules are enough.
if models with 2d elements you also need to define the thickness, just the third missing size.

I'm not an engineer.
However it is clear, with laminator I get the apparent elastic modules of my real laminate.
at this point the fem combines them with the geometry of the solid considering surfaces and thicknesses.
Clearly, I don't have any more questions, the head is prosciolto. :

hello to all, I would remind you that I basically gave up doing a serious structural analysis, given the complexity of such analysis on composite materials.
I have also done an in-depth course, but I miss the basics.
But I have a question to ask.
I'm still inclined to try to dimension simple structures and then finish the job to those who are more competent and I'm trying to scan&solve.
the question is this: scan&solve to be able to insert a customized material asks me the following parameters.

density, elastic modulus, poisson ratio, yield strenght, tensile strenght, compressive strenght, and between failure criteriaon indicates me von mises, maximum shear, rankine, coulomb mohr and modified mohr.

I do not find these failure criteriaon in the apparent module that gives me the laminator.
How can I do that? for the other parameters I should be there, but a confirmation wouldn't hurt.

Thank you very much in advance.

the failure criteriaon of your fem are related to metal materials and not to composite materials.
The only way to have a correlation is to assess the maximum strain of laminate and modeled structure not the fem.

Is there no way to use scan&solve? is so convenient, it does the analysis using utilising mesh.
you know I also bought femdesign, but unfortunately it only supports cloud surfaces and it is a disaster to draw what is needed to me with a mechanical cad.
Please help me. Is there really no way to get close? Not even with an isotropic laminate?
Thank you very much. :smile:

Unfortunately I don't know scan&solves.
However if you plot strains and compare them to the maximum strains you have of laminate analyzed with laminate modeller you are at good point
