Supplementary material to: Finite-size effects in the interfacial stiffness of rough elastic contacts

Abstract

In this supplementary materials section, we provide (i) additional information on the numerical simulations of the main work, (ii) the derivation of all prefactors in the analytical theory, and (iii) unpublished experiments of the contact stiffness of a polymer pressed against a rough substrate.
