      can you show the frictional contact properties.
      Cheers, Ram

      Here I am attaching the screenshot of frictional contact properties sir. Re-entrant honeycomb structure is placed between two plates. Top and bottom plates are flexible (I tried with rigid also, Which stiffness behavior is correct sir?) with structural steel material chosen from material library. Contact body (middle part) is assigned with PLA (Polylactic Acid)(defined multiniear isotropic hardening ) and target body (top plate) as structural steel. Hope I have shared the required details. Thank you sir.

      Hi, can i get a response for the above problem?

      I tried the simulation with bonded contact, and got the force reaction. But, the results are nowhere relevant with experimental results. I tried end time in analysis settings between 0.001-0.0001. How can i find correct end time? When i observed the reaction force, some of the intermittent forces are in negative. I don't understand why it is in negative. I have attached the load (N)-displacement(mm) trend for your reference. Thank you.
