Calculating Stiffness in ANSYS Workbench

[Kanterbrau]

Hello,

I'm currently working on ANSYS Workbench, and I'm looking for a tool to calculate the axial stiffness of a part. I previously try to do it by applying a force on the top, and considering the deplacement (Stiffness = F/Displasment) But I definitly does not work! (my part is more or less a bellow)

If anyone could help me...
Thanks & sorry for my (bad) English..

Hi,
Apply displacement to the part /or load
Then select a node
check stress-strain response
by these values, you should be able to calculate the stiffness.
