Simulating silicon/hyper elastic material

      I am trying to simulate my model using soft and elastic material.

      But the deformation value produced is not feel logical.

      So I tried a simple structure with pure silicon which is already available in ANSYS material library. Still I am not getting a reasonable deformation result. Did I missing some basic setting / properties.

      Hi,
      I suppose the applied load (Force) on the end face of part 1, if it is true then in that case deflection based on applied load of 10N, may lie in the range of 3 X 1E-5. Could you please check the units are consistent everywhere for example creating the geometry, defining material properties, loads, etc.
      Thanks
      Manish

      Yes, I have verified the geometry dimensions and the material property is not defined by me, I have taken the pure silicon from Ansys material library .
      When I edit the direction of force I am getting the mentioned deformation at 100 N force, for 10 N deformation is on micrometer range

      Silicon is a very hard metal.
      Silicone is a very soft elastomer.
      You have picked the wrong material.
      You should use a hyperelastic material model. It is ideal if you can measure a sample of the material you want to use in a material characterization lab. If you don't have the time or money to do that, you will have to search on the internet and hope you find something close to the material you want to simulate.
