Abstract :In this study, some physicomechanical characteristics of black chickpea grains, which have rich content, were investigated. Dimensional and volumetric properties, colour characteristics, and frictional and mechanical properties were examined within the physicomechanical properties of the grains. Compression tests were carried out for the behaviour of black chickpea against mechanical force, both force and deformation characteristics of black chickpea grains were determined, and they were used at three different loading speeds insert ignore into journalissuearticles values(30 mm min-1, 50 mm min-1, 70 mm min-1);. The size dimension, such as width, length, and thickness values, were found as 6.68 mm, 8.85 mm, and 6.26 mm, and the mass was 0.25 g, respectively. The highest $a^*$ and $b^*$, $L^*$ values were determined as 4.31, -0.27, and 18.87, respectively. The values of the static friction coefficient of the black chickpea grains on different friction surfaces insert ignore into journalissuearticles values(PVC, galvanized sheet, laminate, plywood, and rubber); were observed on the rubber surface with the highest. In the mechanical test results, the highest force value was found on the 50 mm min-1 width insert ignore into journalissuearticles values(Y-); axis, and the highest hardness value was found on the thickness insert ignore into journalissuearticles values(Z-); axis at the 30 mm min-1 loading speed.
