Abstract
The present paper is focused on loading-unloading features and hysteresis during indentation of surfaces having a superficial hairiness. Friction between the pile and the indenter and between bristles constituting the pile has been modified in experimental and modelling approaches. The results highlight the influence on stiffness and hysteresis of the friction between the bristles and between the indenter and the bristles. For an oriented straight pile with a fixed length, the indentation behaviour is strongly influenced by the friction between bristles. For a pseudo-random structure in terms of bristles orientation and length, the inter-bristles friction has a lower influence than the friction with the indenter.
