Subject: Youngs Modulus as a Function of Temperature?

Hi Everyone,

I am rite now dealing with a structural analysis.
My aim is to create a Functionally Graded Material.

I want to vary the Young's Modulus (elasticity) exponentially, not in
stepwise manner.
I can do the changing of material by MP, MPCHG commands and then assigning
the EX( elasticity ) to it. But this results in Stepped variation.

For exponential variation,

I have to introduce temperature to all elements

Define a function that makes elasticity temperature dependent.

Keep Coefficient of Thermal Expansion to avoid thermal intervention into
model.

How can I do these above steps?
Are there any specific commands?

The experts out there please explain me a procedure to do this ..


Thank you

Waitin in Anticipation
