Mechanical behaviour of several layers of selected plant seeds under compression loading
This article is focused on the determination of the mechanical behaviour of several layers of plant seeds namely; garden pea (Pisum sativum L.), common bean (Phaseolus vulgaris L.), common sunflower (Helianthus annuus L.) and jatropha (Jatropha curcas L.) seeds under compression loading. The results...

| description | This article is focused on the determination of the mechanical behaviour of several layers of plant seeds namely; garden pea (Pisum sativum L.), common bean (Phaseolus vulgaris L.), common sunflower (Helianthus annuus L.) and jatropha (Jatropha curcas L.) seeds under compression loading. The results from the experiment showed that during compression plant seeds may change their mechanical behaviour that is deformation characteristic ceases to be a function of growing and beginning to resemble that of trigonometric functions and this behaviour is called the "wave effect". Also the strain value at which there is no further change of the mechanical behaviour is actually a local maximum of deformation characteristic and this is called the limit deformation. Exceeding this value can cause vibration of the presser including other negative factors which influences the process of pressing. The amounts of the limit deformation, strain energy and volume energy for jatropha, common bean, common sunflower and garden pea were determined in this experiment. From the calculated amounts of the volume energy, garden pea had the best resistance to change in the mechanical behaviour due to the fact that its change in the mechanical behaviour was not discovered. The other plant seeds; common beans, common sunflower and jatropha with respect to resistance to change in the mechanical behaviour followed in that order of magnitude. |
