Hi Nick,
Augmented Lagrange formulas can be applied to nonlinear solid body contact of faces. The magnitude of the contact stiffness kNormal having less of an impact on the Augmented Lagrange method. The Augmented Lagrange technique allows for some controlled contact penetration. 
I would suggest following the link that I have attached below for more detailed solutions.

Interface Treatment- How a contact pair's contact interface operates is specified by the Interface Treatment property. When the contact type property is set to frictionless, rough, or frictionional (nonlinear contact), this setting becomes visible.

Adjust to Touch: An initial stress-free condition is created by closing off any gaps and ignoring any initial penetration.To ensure that initial contact happens even in the presence of gaps, this option is helpful. If there are any initial gaps, the bodies can fly apart if you don't use this parameter.

Follow the attached link for more details.
