Laminate panel 3 pts bending test with RADIOSS

Jocelyn THIRIOT

Hello there,

I am inexperienced and trying to perform 3 point bending tests on composite panels with Radioss for formula student. I already had some advice but I'm stuck again. I'm trying at first to do the test on only a few plies. Later I will try to add honeycomb etc.
By the way, when I'm at this step, should I make a contact between the upper shell plies, the honeycomb in Solid and the lower shell plies?

Regarding the current model, I can't get it to work. First I got the following error:
--- PROPERTIES 1 ERROR(S) |
|--- 1 ERROR ID : 760 |
| ** ERROR TRAPPED |

Afterwards, I modified some properties but I still have errors. I don't understand which parameters to modify and which are my errors:

Thanks a lot for your help

PS: I am working with RADIOSS 2019 in my school, I can't open your edit 2020 file

Hi

it seems you are missing to define some cardimages for the composite properties.

if you are using /PLY and /STACK you need to use /PCOMPP as property. Please refer to the article:

Tips and Tricks: /PROP/PCOMPP, /PLY and /STACK error id 1241 debugging

if you are defining the ply and stack using /PROP/TYPE19 and /PROP/TYPE51 you need to do differently. in this case, the laminate definition need to use /LAMINATE

Please refer to the attached deck that i set the composite property.

there are other warnings that you will need to check.
