How can I define variable material properties?

How can I define variable material properties?

How can I define variable material properties?

(OP)
How can I define variable material properties (example variable modulus of elasticity)by using ANSYS 6.0?

How can I use sinusoidal form static surface load?

thanks...

RE: How can I define variable material properties?

Can you elaborate a little bit on that, more precisely, your modulus of elasticity will be variable with respect to what ?

To load your model with a static sinusoidal shape, the simplest way should be to store the nodes to be loaded in an array, then use their coordinates (using NX, NY and NZ) to build the load shape.

! Here select your nodes, and
! the number of the lowest
last_node=lowest_node_number
*DO,I,1,NbNodes,
    curr_node=NDNEXT(last_node)
    curr_x=nx(curr_node)
    curr_y=ny(curr_node)
    curr_z=nz(curr_node)
    f,curr_node,fx,COS(2*PI*curr_x/lambda_x)
    f,curr_node,fy,COS(2*PI*curr_y/lambda_y)
    f,curr_node,fy,COS(2*PI*curr_z/lambda_z)
    last_node=curr_node
*ENDDO

See at the end of the *GET function, if you don't know these commands.

Good Luck

RE: How can I define variable material properties?


I'm working on FGM (Functionally Graded Material) and I wish  finding stress distribution subjected of sinusoidal shape static surface load and simple supported by Functionally Graded Beam.
 I couldn't apply code that your send me, because of, would you write me an example and solution of this example about  subjected of sinusoidal shape static surface load.
 Thanks...
