Abstract
This paper deals with the possibility of reducing the sliding resistance of soil
against bulldozing plates by using unsmoothed bionic surfaces imitating the
surface morphology of the head top plate of underground living animals.
Microscope (SEM) observations of the morphological microstructure of the
body surface of dung beetles (Geotrupes stercorarius) were focused on the
bulldozing plate on the head used to groove and pull the soil. The micro relief
showed a surface made of humps and dips with a general arrangement
constituted from irregular hexagonal or parallelogram patterns.
Based on these observations, twelve plates (approximately 152 x 200mm)
were constructed. One was flat and taken as a reference. The eleven others were
adapted with circular humps or dips having the form of a portion o
