Characterization of soil parameters of two soils of Rio Grande do Sul in modeling the prediction of tractive effort
Machado, Antônio Lilles Tavares; Trein, Carlos Ricardo (2013) [Artigo de periódico]The interaction between the soil and tillage tool can be examined using different parameters for the soil and the tool. Among the soil parameters are the shear stress, cohesion, internal friction angle of the soil and the ... -
Draft prediction models for soil engaging tines in two soils of Rio Grande do Sul, Brazil
Machado, Antônio Lilles Tavares; Trein, Carlos Ricardo (2013) [Artigo de periódico]The draft forces of soil engaging tines and theoretical analysis compared to existing mathematical models, have yet not been studied in Rio Grande do Sul soils. From the existing models, those which can get the closest ...
