Hi,
As the title states, I am trying to reproduce a sample case for HGO in FEBio that is available in Abaqus documentation (INP file). I modified the input file (attached as feb) to load the whole upper surface with a displacement load (instead of a concentrated force and linear constraint as in the original input file) to make FEBio implementation easier (I did not find linear constraints in FEBio Studio, though I know they can be added to FEB file). I used the uncoupled HGO (incompressible) in FEBio, with the material parameters from Abaqus documentation (except for the shear modulus: c[feb] = 2 * C10[abq]) and changed the material axes to be able to use the same angle (49.98°). I can not get similar results (stress, reaction force in N1). What am I missing?
Versions: FEBio Studio 1.6.1 (FEBio 3.5.1), Abaqus 2021 SE.
I appreciate any help you can provide.
