Efecto de las condiciones fisicas del suelo y de las rejas de sembradora de cereales en el valor de la fuerza que provoca su rotura pasiva


, : Efecto de las condiciones fisicas del suelo y de las rejas de sembradora de cereales en el valor de la fuerza que provoca su rotura pasiva. Interciencia 26(9): 391-393

A mini soil bin was used to evaluate the effects of soil physical conditions and the blades of cereal seeders (one straight and one curved) in the value of the force that produces passive failure. The test was made at 12% humidity, 1.15 Mg/m3 density, 12cm depth and rake angle of 50degree.

In practice, this often means that we are bound to use sparse meshes in the model for the forward prob...
