Change Stiffness between nodes on a 2D element beam 1

[JCastas]

Dear all,
I have done a simple beam with 20 nodes of 2D elements in ansys APDL. I would like to change the stiffness value between two nodes (like a damage simulation).
Is there any way o do this?

Thank you in advance.

Hi João,

Select the element linking your two nodes then :
Emodif,all,MAT,X
With X a second defined material
Or :
emodif,all,secnum,X
with X a new cross section for your beam element

But I don't do damage simulation so I don't know if this is the right way to model damage.
