Abstract
A method for continuously measuring the stiffness and area of contact between two bodies is provided. Elastic stiffness of a junction is measured by introducing a relatively small oscillatory mechanical force at a known frequency to the junction and measuring the subsequent displacement response using AC signal-handling techniques to provide a continuous measurement proportional to the stiffness and the area of contact between the bodies, even as the area of contact changes.
