The shell contact surface would still be offset from the reference surface by half a contact thickness (contact thickness = shell thickness unless overridden by variables on Card 3 of *CONTACT). Thus the shell contact surface would encounter another body first. If excessive penetration of that contact surface is observed, possible remedies would be to increase the contact thickness and/or increase the contact stiffness (see Card 3 of *CONTACT).
