Abstract

The load history that blade/disk contacts in jet engine attachment hardware are subject to can be very complex. Using Finite Element Method (FEM) to track changes in the contact tractions due to changing loads can be computationally very expensive. For 2D plane strain contact problems with friction involving similar/dissimilar isotropic materials, the contact tractions can be related to the initial gap function and the slip function using coupled Cauchy Singular Integral Equations (SIEs). The effect of load history on the contact tractions is illustrated by presenting results for an example fretting "mission". For the case of dissimilar isotropic materials the mission results show the effect of the coupling between the shear traction and the contact pressure.
