Finite element simulation of high cycle fretting wear using an implicit adaptive cycle jump

Fretting motion between two contacting solids can, under gross slip conditions, induce wear. A finite element model and a simulation strategy aiming at predicting wear under fretting motion are presented. The numerical results obtained are compared with experimental data from the literature. The proposed simulation process is particularly suitable for computing high numbers of cycles. To this end, a cycle jump technique is used, and different integration schemes are investigated. Results show that instabilities may arise when an explicit scheme is used, which limits the size of the cycle jump. On the other hand, using an implicit scheme involves a trade-off between the possibility of considering a larger cycle jump and the number of iterations required for convergence. It is shown that the more cycles we perform, the faster the implicit scheme converges. Therefore, the implicit scheme is especially appropriate for high-cycle computations. Moreover, an adaptive cycle jump is used with the implicit scheme, enabling to accelerate the computations for high numbers of cycles.
