Question about conductive transfer on Abaqus

[Antoine Dupon]

Hello,

Could someone explain to me how to numerically simulate the conductive contact via screwed connections on Abaqus?

Thanks for your feedback

 

[FEA way]

You can use either tie constraint that will allow for perfect heat exchange between the surfaces or contact with gap conductance. Setting a small value of this parameter makes it harder for heat to flow through the interface. You could also set a very large value to make it work like tie constraint.

Okay, but on Abaqus, where do I define that?

 

[FEA way]

Gap conductance is here:

Create Interaction Property —> Contact —> Thermal —> Thermal Conductance

If you want to define tie constraint go to:

Create Constraint —> Tie

Ok thanks for your response

I have a last one question
I have to put a conduction on a solid with a temperature of 40°C on a surface of 50°C, how do I calculate the heat flux, which I will fill in on Abaqus?

thanks for your response
