Material properties as function of RD

[mmmbordo643]

Hi all,

I need to express Youngs modulus and poisson's ratio as a function of Relative Density in ABAQUS Standard. Any ideas or insights on how to do this?

Thanks,
Chris

How does the density vary in the model? If it varies with temperature or spatially then express E in the same relative manner.

can you offer any suggestion on how this would be done? Density in this case is varying spatially.

Thanks,

You'd have to use a subroutine, UMAT, I believe. The co-ordinates should be available to use as a variable there.
