    FEA testing of Stiffener Inserts

    J. B.

      Hi,

      I'm trying to test various materials to use as inserts to reinforce (stiffen) a plastic moulding, however I think I might be missing something as the results seem a bit variable.

      The first picture shows the two parts, the reinforcement insert (in purple) and the plastic frame (in grey).

      I've used  'fixed geometry' on a face (the one shown in green in the first image) and used the default 'global contact - bonded as the way of combining the two parts.

       

      I applied the load to the face of the  insert (purple), and also to the outer face of some ribs on the moulding, using 'total force' (second image)

      I also used the default mesh.

       

      When I check the maximum deformation for various materials they don't seem to correspond to the materials relative stiffness ( re the elastic modulus value ).

      Not sure if I'm missing something?
