Functionally Graded Material

Functionally Graded Material


I want to model a functionally graded material(FGM) in ABAQUS. I am  reading literature and most of the people of modeling in ABAQUS, I am still trying in the process of reading information about FGM.

Can anybody who have developed FGM in abaqus guide me the way to go?

Thanks for the time.

RE: Functionally Graded Material

I did not developed any FGM related model, however, my understading of FGM is that the material properties are dependent on spatial coordinates.

If so, for modeling a FGM you can:
-assign different material properties to individual elements
-make the material properties dependent on field variables and change the value of field variable at different nodes according to the spatial distribution of the material properties.
-write your own constitutive subroutine, which is is supplied with the material point coordinates, and therefore allows local modeling of the material response

eBook - Functional Prototyping Using Metal 3D Printing
Functional prototypes are a key step in product development – they give engineers a chance to test new ideas and designs while also revealing how the product will stand up to real-world use. And when it comes to functional prototypes, 3D printing is rewriting the rules of what’s possible. Download Now
