i want to create a plate model with FGM properties the specifications are as follows
length of plate = 2
height of plate= 3
young's modulus variation E(X) = E1*exp((log(E2/E1))*x)
where E2 = 100
E1 = 200
First divid the plate as for example 20x30 mesh elements
let x direction along the length of the plate which equals 2
use a simple program to calculates the variation of E (x) along x about 20 different vlaues
assign these values for each
Hi Sahil,
In ABAQUS you can easily do that using UMAT (User defined material subroutine). However, in ANSYS, I was not familiar with if you can define user material model, but a simple google search tells me that in ANSYS also you can define the same (http://www.ansys-blog.com/davide-usermat-blog/http://www.ansys-blog.com/davide-usermat-blog/). Hope this helps.
Thanks,
Anshul
Here is some more help on Ansys UserMat.

hi sahil sir,
i am facing the same problem..can you please share with me how did you construct the FGM model in Ansys??
thanx in advance..
