Effect of Moisture Content on Mechanical Properties for Some Varieties of Cereal Grain
|
|
Abstract: , shear force and shear stress at both longitudinal and lateral directions was determined for some varieties of rice, wheat, corn and barely.
The results showed that for all studied crops, hardness, shear force and shear stress showed an opposite linier dependence on moisture content. Therefore, the values of grain hardness within the investigated range of moisture content ranged from [(21.76-37.50), (88.07-173.20), (24.012-50.44), and (40.35-81.54) N] for the investigated varieties of rice, corn, wheat, and barley, respectively.
Meanwhile, shear force at the longitudinal direction was higher than lateral direction for the investigated varieties of rice and barely, while it was lower at longitudinal direction than lateral direction for corn and very close at both directions for wheat.
Also, the values of shear stress in lateral direction were higher than in longitudinal direction for all varieties of the investigated crops, while it ranged from [(3.34-10.79), (2.17-6.99), (2.723–6.04), and (4.17–8.732) N/mm2] for rice, corn, wheat, and barley, respectively, within the investigated range of moisture content.
