Mechanical behaviour of several layers of selected plant seeds under compression loading

摘要: Herak D., Kabutey A., Sedlacek G Ű rdil G., 2012. Mechanical behaviour of several layers selected plant seeds under compression loading . Res. Agr. Eng., 58: 24–29. This article is focused on the determination mechanical namely; garden pea (Pisum sativum L.), common bean ( Phaseolus vulgaris sunflower Helianthus annuus L.) and jatropha (Jatropha curcas loading. The results from experiment showed that during compres sion may change their deformation characteristic ceases to be a function growing beginning resemble trigonometric functions this called “wave effect”. Also strain value at which there no further actually local maximum defor mation limit deformation. Exceeding can cause vibration presser including other negative factors influences process pressing. amounts deformation, energy volume for jatropha, bean, were determined in experiment. From calculated energy, had best resistance due fact its was not discovered. seeds; beans, with respect followed order magnitude.
