A test of fretting between titanium alloy and stainless steel is conducted, with the concept that the friction coefficient is regarded as a variable rather than a constant. The aim of this experiment is to simulate the real working structure of a dovetail joint commonly used in aeroengine components and other related mechanical engineering applications as well as to calculate its contact parameters by means of the Boundary Element method. One of the most important findings shows that the maximum shear stress is lower than usually considered when taking the friction coefficient as a variable into account, since it behaves naturally.
