Linear perturbation analysis in ABAQUS with surface to surface contact

Choose a channel featured in the header of iMechanica: 

Hi, I tried a Linear perturbation analysis in ABAQUS with surface-to-surface contact. The parts that are defined as contacting surfaces are 0.2mm apart. They are also given a normal behavior with a pressure overclosure option using "hard" contact. However, in some modes where it is expected to be in contact, there is interpenetration. The problem is that it depends on the scale of deformation too. So my question is how to make this generalised, i.e., include no contact in case of tensile mode behaviour and include high stiffness in case of mode involving compressive type behaviour?
