Webon direct measurement of the soil-pipe bulk friction coefficients (both, dynamic, and static) for the coating systems of interest. The coating systems were applied in accordance with relevant AWWA standards (AWWA C205-07, AWWA C214-07, and AWWA C222-08). Variables included overburden pressures, type of coating material, soil type, and soil WebThe stainless steel wire generated less friction than nitinol, and friction increased in the presence of artificial saliva in comparison with air alone. These results show that, under experimental conditions, ceramic brackets, nitinol arch wires, and saliva all increase static frictional resistance. Publication types Comparative Study MeSH terms
