“…On the basis of the literature [35][36][37][38], it is clear that the influence of the phase difference on the hysteresis characteristics of the friction force cannot be ignored. The load phase difference affects the fretting fatigue life by changing the timing of the contact friction force intervening and affecting the fretting wear.…”

Tenon-jointed turbine blades will be impacted by airflow and centrifugal force during the high-speed rotation of the engine. The surface contact stiffness of the tenon and tenon groove will change with complex external loads. Through the analysis of the micro-morphological characteristics of the contact surface of the tenon joint bladed disk, the contact characteristics of the asperities on the rough surface are determined. At the same time, to solve the problem that the traditional microscopic contact stiffness calculation formula cannot be applied to the tangential displacement load, the periodic piecewise tangential stiffness expression is derived based on external loads of the normal force and the equivalent tangential force. Furthermore, this paper studies the properties of the tangential stiffness curves under different external load frequency ratios and phase differences. An increase in the frequency ratio will decrease the step value of the piecewise function and make it tend to a smooth transition. The change of the phase difference will directly change the monotonicity and fluctuation of the stiffness curve. The macro and micro theoretical analysis methods of contact characteristics have been established.

“…Nonetheless, the most time-consuming problem to run was solved in less than 9 seconds. This configuration has been chosen because it is commonly used for fretting fatigue experiments [6] , as shown in Fig. 15.…”

“…Fretting problems can be investigated using analytical, numerical and experimental procedures. The most common approach to the numerical analysis of fretting problems is the Finite Element Method (FEM) [4,5,6]. However, contact is essentially a boundary phenomenon so it could be expected that the Boundary Element Method (BEM) would be an interesting alternative to this kind of problems.…”

“…A comparison with conventional BEM [9], using Lagrangian polynomials as basis function, shows that the IGABEM is more accurate if we consider the same number of degrees of freedom. Furthermore, if we compare to commercial finite element method [6], the necessary number of degrees of freedom for reaching the same accuracy of IGABEM is thousands of times bigger for the finite element method. This demonstrates that IGABEM is a very suitable method for calculating the stress distribution in contact problems with cyclic loads that can cause material failure due to fretting fatigue.…”
