The aim of this research study the effects of some engineering properties of green peas grown in Egypt at different moisture contents of 45and 57w.b.% (wb) . Knowledge of physical and mechanical properties of green peas seeds are essential for the design of equipment’s to handle, transport, process and store the crop. The moisture content of green peas is different at the harvest than at storage; thus affecting different physical and mechanical properties of the green peas. It has been identified axial dimensions, mean diameters, length, width ,diameters, sphericity, surface area, and angle of repose of green peas were determined using standard methods. The physical properties of green peas seeds were dependent on the moisture . The average length, width, thickness, geometric mean diameter, thousand grain mass, angle of repose and surface area of peas seeds ranged from 8.19 to 8.50 mm, 7.6 to 7.8 mm, 7.1 to 7.4 mm, 7.62 to 7.89 mm,360 g to 422g,25° to 30° and 182.18 to 195.33 mm2, respectively. The influence of different moisture levels (45and 57 w.b.%), in two loading orientation (longitudinal and transverse) and tow loading speed (6 and 8 mm min-1) on the mechanical properties of peas such as maximum deformation, rupture force of peas was investigated. The rupture force increased from 39 to 45 N, as the moisture content decreased from 57 to 45 % (wb). It was observed in the mechanical properties that moisture changes were effective on maximum deformation, rupture force. Also loading speed was effective on maximum deformation, rupture force.
