Abstract
The existing analytical solutions for determining an average coefficient of friction in bending under tension tests
are revisited. The most commonly used equations are based on the
assumption of uniform pressure in the contact interface, which is proven
to be a statically inadmissible assumption. New analytical solutions
are presented based on the assumption of concentrated forces, which are
shown to be statically admissible. Existing literature supports the
existence of localized peaks in the pressure distribution in terms of
both numerical simulations and experimental results. Due to the
inhomogeneous pressure distribution, bending under tension tests are not
considered appropriate for determining the coefficient of friction, but
rather a qualitative test capable of relative comparison of
tribo-systems.
