stiffness

I'm simulating the interface between a steel plate and the fire proof coatings covering the steel plate. The elements i use in the simulation is contact 173 with a material property of debonding,which is defined as cohesive zone model.(CZM)

 CZM in ansys provides  TBDATA such as maximum contact stress,contact at the completion of debonding, but what's the problem is that I failed to set the initial contact stiffness. it's true that ansys provides FKN to define the contact stiffness, but it's just a stiffness factor.

Hi,

As a part of my research, I would like to break down a simply supported beam to two beams shown in the attachement.  I expect to remove the bond and use of springs for transforming deformation of upper beam to lower beam. What could be the stiffness of springs which could be used in new model?

Thank you for your comment,

I want to get stiffnes matrix from ANSYS Classic. I used substructure analysis and using list->other-> super element data and got stiffness matrix of whole structure. But I want to get stiffness matrix of individual elements. Can I do it in ANSYS Classic?
