Nice presentation. A good overall look at a complex modelling and analysis issue.

Can I get full video of setting of ply and insert because I am beginner

Hello mate, I have a doubt about laminate options. I don’t know what is the difference between total laminate or smear core laminate, because when I use one of them, I obtain very different results

[@Freddie1M]

Where do you manage the units? Where is the option to input units? (11-13 mins in)

First of all I have to Say that I'm not an Expert in Altair, so take my words with their value. I had the same questions some mounth ago, and I have to Say that Altair works with a parametric system of measures. So, there Is a certain number of combinations of ünit of measures you can choose within. For example, with the One that I use, I have to think at lengths in mm, masses in tons, pressures in MPa and forces in N. I Hope this has bene huseful for you

What is meant by shuffling optimization? Kinda sounds like a variation of a genetic optimization. Does anyone know where I read more about this topic?

[@Rodrigomartins86]

It's not about the method, but the optimisation problem. In shuffling, you are shuffling the composite plies like a card deck.

please, can we get a link to downlod the part

[@dorianvincent2101]

We cannot do this tuto with Altair Student

[@95pdp]

Is it possible to export the geometry of flat patterns of the plies?

[@lewis72]

It is, I did it. I generated Surfs from FE.

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
