indentation with peridynamics

Hello,

I’m trying to fit an indentation curve (force-depth) from finite element method using the lps model.
It seems reasonable to use the same material parameters (bulk and shear modulus) than in
the FEM simulations. However the results I obtain with peridynamics are really huge (the force)
compare to FEM (several order of magnitude). Do you have an idea why?
