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)).
