Rubber Block

Attached is a simple model of a rubber block (non-linear properties). I am having some problems with its material properties.


I have satisfied all the necessary fields in order to define the material, but I think the stress-strain curve I am using is causing some problems (derived from experiment).


Model details:

  • Symmetry constraint on 2 side faces.
  • Load currently just a 1 N force applied across top and bottom surface. (force vs time .dat file exist not applied yet to simply problem)
  • Automesh
  • Used reference geometry on bottom surface


I am pretty sure the problem lies within the material properties. I have simplified all the variables and it seems to solve if I use a simple material


Could someone please help. Thanks
