Abstract Experiments were conducted to determine the effects of surface texture and normal load on the stiffness of joints formed by two machined surfaces. The experiments involved deformation measurements and examination of the contact surfaces of joints subjected to normal loads. It was shown that surface-displacement results can be affected by assuming that the compressive strain in the joint specimen is the same as in an equivalent solid piece. The elastic stiffness of joints were found to increase with an increase in the maximum nominal surface pressure. Results were also shown to illustrate that the elastic stiffness of a joint is affected by the loading history. Surface-profile measurements indicated that the topography of a joint surface changed with normal load, and that the deformation of a surface profile was related to the permanent change measured by extensometers placed across the joint interface.
