HELP with ABAQUS Subroutine to change element material properties

HELP with ABAQUS Subroutine to change element material properties

HELP with ABAQUS Subroutine to change element material properties

(OP)
Hi, I'm trying to do a subroutine that works as follow: I want to introduce a temperature limit condition to each element of my model. If the element reach a temperature value, I want to change its electrical conductivity properties. (I'm doing a Coupled thermal-electrical analysis)

Which type of Abaqus Subroutine I have to use? UEL, HETVAL...?

Thank you!

RE: HELP with ABAQUS Subroutine to change element material properties

Not sure which one to use, or how to do this, but have you considered just using the standard temperature dependent properties (e.g., electrical conductivity), within CAE?

For instance if the electrical conductivity becomes twice as large (200 from 100) at a certain temperature (say 100 degrees), thus a step function, then one could give the following table for the temperature dependent electrical conductivity in CAE:

El.C Temp
100 0
100 100
200 100.01
200 1000

This will be valid for all elements using this material property.

RE: HELP with ABAQUS Subroutine to change element material properties

Yeah, the built-in option should be checked before.

In case a subroutine is really needed, then I would look at the USDFLD and the usage of field variables.
As always, the manual explains the details.
