CONTACT BETWEEN ROUGH SURFACES : CRYSTAL PLASTICITY INFLUENCE ON THE CONTACT TIGHTNESS ESTIMATION

Durand, J. ; Proudhon, H. ; Cailletaud, G. ;

Full Article:

This paper is devoted to analyse the influence of material behaviour in a normal frictionless contact between a rough surface and a rigid plane. By means of Finite Element code Zset/Z´eBuLoN, crystal plasticity models are determined and compared to a von Mises elastoplastic behaviour. The influence of grain orientation but also elastic anisotropy are put forward. Stress distributions, cumulated plastic strain, global responses and fluid flow in the resulting aperture field between surfaces are then quantified and compared.
