FGM plates are developed in ANSYS easily in APDL rather the GUI and if you are working in Workbench then it may not be possible to do so. Yes the next major point as the FGM is the continually varying in thickness or in an other direction then you need to write a function related to the properties and in ANSYS it will be developed as layerwise process and the functions will be given based the discrete with the function and as the number of layer will increase it will be more precise.

thank's Dr. subrata if i understand you , i need to do a multiple layer with a different properties

Dr. Subrata's suggestion is good one, but also you can make the plate made of solid elements and across the thickness assign to each row or elements material with variable properties in the fashion you wish. This option allows for better capturing the thru-depth strain variation and shear, rather than use of layered plate elements that is limited to low order shear theories.

Thank's

Dear Mahmud

But how can we set variable properties in each element?

Thank's but any one had a demonstrated apdl code

We can use layered elements with properties assigned to each layer or use a solid Shell element in ANSYS and assign element properties to each layer of elements. This process can be cumbursome , so one can write an APDL script to select all the elements on a given plane and assign one property to all of them and further on for each plane. By plane i mean all the elements at an equi-distance from a reference plane(origin). This works well for geometries with some kind of symmetry.. but for arbitrary geometries we have to think for something else.

Thank's mr kumar

Thank you Drs

The problem is solved 

@Bendine Kouider, please take a look at my paper

Thank you ahmed 

Hi Mr. Bendine

I am working on FGM as well and facing the same problem as you were. I wanted to ask what solutions did you get for your query?

Dear Chugh

please check my paper, it explains in details how to model an FGM plate with ansys, and u also can find the code in the appendix

hope its help

kouider

Thanks dear Bendine for share your paper.

Dear Bendine

how to provide/assign variable properties to each layer in APDL? will You please provide me so..

Dear kouider

It's nice paper and good suggestion for simulation of fgm

The 'do' program is good for when the material variation in one direction but if the material is required to vary in Two directions then how to modify 'do' codes
