Indentation Testing trouble
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.
attached are some images to add context.
