The relationship between static and kinetic friction for plant granular materials

Artur Wójcik , Jarosław Frączek , Magdalena Niemczewska-Wójcik


The article shows a direct relationship between the maximum frictional force Fst (static friction) and the mean frictional force Fkin (kinetic friction). The tests were carried out for three plant granular materials (peas, maize, triticale). The modified Amontons-Coulomb model of friction was proposed for the Fst and Fkin description. The additional statistical analysis showed a strong linear correlation (R2 = 0.95) between the Fst and Fkin forces for all combinations of moisture levels (9, 12, 15, 18%) and loads (16, 27, 42, 50, 61 N). This makes it possible to simplify the measurement procedure, which in the case of kinetic friction is relatively difficult to implement.
