Modelling adhesive with dependency to temperature

Altair Forum User

Hi all,

 

I want to perform a simulation of a hybrid structure which is joint by screws and adhesive. The objective is to investigate the behavior of the hybrid materials under thermal load. Therefore I want to ask, whether there is the possibility to give the adhesive area different material cards in dependency to the temperature. So that the adhesive is not stiff at the beginning but inceases its strength according to the temperature.

I want to use Nastran or Optistruct.

 

Thank you for the help

Hi,

 

I think modelling adhesives with different temperature dependent material property this maybe possible.

 

You can use MATT1 to include temperature dependent material properties via TABLEMi card.

 

Please refer to help for more information on MATT1.
