Comparison of the Mechanical Behaviour of Selected Oilseeds under Compression Loading

摘要: The present study provides information about the comparison of mechanical behaviour selected oil bearing crops namely rapeseeds (Brassica napus L.), sunflower seeds (Helianthus annus L.) and jatropha (Jatropha curcas under compression loading. In this research, device ZDM 50 with a chart recorder pressing vessel diameter 100 mm were used to determine relationship between magnitude force deformation characteristics oilseed pressed at initial height 80 mm. From test, amounts true deformation, maximal energy compressive samples calculated also mathematical equations describing limit ratio, ratio point determined. position on curve, that is, first leakage from various oilseeds was determined compared. Based measured achieved highest values followed by seed then seed. amount required for gives indication needed obtaining It found as well force-deformation curve showed varying results due physical inherent characteristics.
