Composites - Radioss

Hi everyone,

I have to simulate an object made by thermoplastic composite laminate. I know that I have to do a model calibration with a fitting of experimental curves but I have a lot of doubts about the correct procedure.

For exemple on the one element test I have to define laminate and plys or I have to use a single ply with laminate's thickness?

Could anyone send me some material about composites model calibration?

Thanks in advance.

Marta

You can refer attached documents for material calibration using HyperStudy.

Thanks @Rahul R for you replay.

I've seen the attached file: there b and n are calculate as image.png.5690a927e3d0ac3e2dc9aa13ad4f2664.png but, I have to use CRASURV model, where b and n are calculate as image.png.ec03c505fd29a21eb0f4e024d00909f4.png (I don't know what Wpref is)

Furthermore I don't know HyperStudy, I'm using Hypermesh (Radioss).

Any other suggestion?

Thanks a lot

Kindly regards
