A normal contact test setup that is capable of measuring the elastoplastic deformation of a joint during loading and the elastic spring-back during unloading has been presented. The deformation is measured by two extensometers, which are clamped at the bottom and at the top specimen. The normal contact behavior of surfaces, which are made of different materials, sizes, and roughness parameters, is tested. The application of two extensometers is necessary to measure the bending, which can occur during the experiments. Finite element models with geometrical irregularities are applied to examine more closely the larger elastic spring-back of unloaded stainless steel surfaces. The determined pressure-approach relationships can, be used for simulations of bolted joints. Geometrical irregularities cause a large scattering of the elastic joint deflection if the contact surface has a small area or is made of a material with a high Young's modulus.
