ANALYSIS OF FUNCTIONALLY GRADED MATERIAL USING ANSYS

Submitted by dineshk on

HI.

I am doing project using ansys.can anyone help me how to analyse functionally graded material using ansys software

Hello,





here are a few links on spatial variation of material properties

Most of them explain the definition in Abaqus, their transfer to Ansys should be feasible

 

1) get this PhD thesis:



DYNAMIC STRESS INTENSITY FACTORS

FOR HOMOGENEOUS AND NONHOMOGENEOUS MATERIALS

USING THE INTERACTION INTEGRAL METHOD

BY

SEONG HYEOK SONG

THESIS

Submitted in partial fulfillment of the requirements

for the degree of Master of Science in Civil Engineering

in the Graduate College of the

University of Illinois at Urbana-Champaign, 2003





The code appears also in

Buttlar, W., Paulino, G., and Song, S. (2006). ”Application of Graded Finite Elements for Asphalt Pavements.” J. Eng. Mech., 132(3), 240–249.

Changing material property over coordinates



You should be able to define your elastic modulus values as a tabular

function of a field variable (set the number of field variables to "1"

when defining an elastic material in the "Edit Material" dialog box).

In this case, the field variable value will correspond to your

Y-coordinate. Unfortunately, ABAQUS/CAE doesn't currently support the

definition of predefined field variables (even though it has tools to

define discrete and analytical fields which can be used in interaction

and load definitions). So, you'll need to edit the input file to add a

*INITIAL CONDITIONS,TYPE=FIELD,VARIABLE=1 section and/or a

*FIELD,VARIABLE=1 section to actually define the field variable values.

Alternatively, you can use the UFIELD subroutine (this might actually

be easier, since the coordinates of the nodes are passed into the

subroutine, and all you'll have to do is set FIELD(NSECPT,1) = COORDS(2)).



Regards,

Dave
