Conical spring’s stiffness

  How can a conical spring's stiffness change when it undergoes significant deformation? I imported the built-in conical spring from SolidWorks into ANSYS Workbench and applied a certain deformation within the elastic range, but its stiffness remained constant, which is inconsistent with theory. What should I do?😖

  Hi
  We have had similar questions in the past in the forum – search the forum for these posts.
  
  Also a paper shows when and how the spring becomes nonlinear and in which regime (depending on the type of conical spring).
  The paper is called:
  ’Optimal design of conical springs'
  Hope this helps.
  All the best
