subroutine young's modulus time-dependency

[EvgenAbaqus]

Hello everyone!

Could you help me please with a simple problem.

I am a PhD student working in the biomechanics field and I should use some "smart" materials. I am doing simulations young's modulus time-dependency

I have never written a subroutine code

I'd like to use some equation [see attached fig.]......

Does anyone have a subroutine sample for modeling young's modulus time-dependency for 2or 3 dimensional model?

Need YOUR Help Guys.

Give us a little background so an appropriate suggestion can be made. What is the application? What kind of analysis are you running? What kind of smart material are you talking about? Where did that E vs. time curve come from? What sort of experiment was performed?

If it is really that dependency only, then there is no need to program a user subroutine.

Either make your E dependent of temperature or field variable and then apply a temperature or field variable with a amplitude during the step.

application of temperature is a good idea) thx
