Determination of some physical and mechanical properties of Barkat variety of broad bean

Abstract

In this research the effect of moisture at three levels (57, 67, and 77 %) on the physical properties of the Barkat bean variety including, including dimensions, geometric mean diameter, volume, sphericity index and the surface area was determined. And the influence of different moisture content levels (67,57 and 77%), in two loading orientation (longitudinal and transverse) and three loading speed (8,6 and 10 mm min^-1) on the mechanical properties of the maximum deformation, rupture force, rupture energy, toughness and the power to break the broad bean was investigated. It was observed in the mechanical properties that moisture changes and loading speed were affective at 1% on rupture force, rupture energy, and toughness. Loading orientation was affective on deformation, rupture power at 1%. The interaction between speed and orientation were effective at 1% on power. The interaction between moisture and speed on deformation, rupture power, rupture energy, toughness was effective at 1% probability. The interaction between orientation and moisture on rupture force and energy was affective 1%.
