Physical properties and effect of loading orientation on the mechanical properties of black chickpea

Abstract

This research was conducted on black chickpea seed.  Physical and mechanical properties of black chickpea are needed for equipment which is used in activities such as transportation, storage, grading, packaging milling, etc.  Properties which were measured including dimensions, thousand grain weight, projected area, geometric mean diameter, sphericity and surface area.  Experiments were carried out at moisture content of 8.15% (w.b.). Results showed that average value of length, width and thickness were 7.996, 5.248 and 5.004 mm, accordingly.  The mean projected area perpendicular to length, width, and thickness obtained 25.283, 28.803 and 30.456 mm², respectively. Sphericity was 74.529%.  Also, some mechanical properties of black chickpea in quasi static loading have been determined such as elasticity modulus, rupture force and energy were used to rupture.
