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 

Ibraheem Hassab-Allah thanks will try this

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.
