Stiffness Matrix to define a material

Hello everybody :slight_smile:

I’m trying to define a material by is his flexibility matrix/stiffness matrix, but I didn’t find a way to do that even with TEDDY. So, I would like to do know if it’s something possible ? I not talking about the command MLAY or FLAY in the module AQUA. I would like to directly enter the stiffness matrix 6x6 for a material. I saw the post by another user about this subject in 2020 so, I’m hoping with the version 2023 there is a tip to do that ?

Thank you in advance for your consideration


If it must be a material definition, using MATE in AQUA is probably the closest you can get.

If you can work with defining the stiffness/flexibility matrix of an element instead, you can use ADDM or FLEX in SOFIMSHA.

Thank you very much for your answer, ADDM in SOFiMSHA is exactly what I’m looking for
