Physical properties and mechanical behavior in quasi-static loading of faba bean (Vicia faba L.)

Abstract

Introduction This research was conducted on faba bean seed (Vicia faba L.).Objectives Knowledge of the physical and mechanical properties of faba bean is required for equipment used in activities such as transportation, storage, grading and packaging. Methods Properties which were measured included dimensions, mass, volume, projected area, density, geometric mean diameter, sphericity and surface area. Experiments were carried out at a moisture content of 88.05% (wet basis). Some mechanical properties of faba bean in quasi-static loading were determined, such as elastic modulus; rupture force and energy were used in rupture. Results Results showed that average mass and volume were 4.12 g and 3.30 mL, respectively. Dimensions increased from 16.65 mm to 28.73 mm in length, 11.97 mm to 21.60 mm in width and 7.31 mm to 11.11 mm in thickness. The mean projected areas perpendicular to length width, and thickness were 143.98 mm2, 192.05 mm2 and 321.65 mm2 respectively. The geometric mean diameter and surface areas were 14.83 mm and 694.13 mm, respectively, while sphericity was 65.48%. Conclusion It was found that the values of these mechanical parameters increased when the loading rate was increased.
