Subject: [Xansys] 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
