Indentation Testing trouble

    • selwootton


      I am trying to model a simple indentation test with a sphere tipped indenter and a cylindrical model. I have quartered the model for computational speed and have had success previously with non spherical indenters but for some reason get alot of noice on the deformation of the model with a spherical indenter.

      It may have something to do with my contacts? or mesh? but I have student version only so my mesh refinement is limited.

      I have tried changing contacts from frictionless, bonded to bonded MPC but none seem to give a good outcome.

      Please help

      attached are some images to add context.

      have you tried to plot contact status? It may be worth plotting it to see if the initial contact was setup correctly. You can do that by adding a Contact Tool.n

      try reducing the element size at the point of contact and use Frictional contact.n
