ABSTRACT
The stress ratio and the coefficient of wall friction were determined experimentally for rape seeds and wheat grain. Behaviour of the grain was analysed during cycles of loading and unloading which simulated conditions of storage in a silo Measured values of the stress ratio correspond to the range of variability obtained analytically for yielding at the bin wall in the active stress case.

Wyznaczanie ilorazu naporu w roślinnych materiałach sypkich. Cz. II. Badania doświadczalne
iloraz naporu, współczynnik tarcia, złoże ziarn
W pracy omówiono wyniki badań doświadczalnych ilorazu naporu i współczynnika tarcia nasion rzepaku oraz ziarna pszenicy. Analizowano zachowanie się złota nasion podczas kolejnych cykli obciążania i odciążania symulujących warunki magazynowania w silosach zbożowych. Wartości doświadczalne pokrywają się z zakresem zmian ilorazu naporu wyliczanym z zależności analitycznych przy założeniu uplastycznienia materiału przy ścianie zbiornika w czynnym stanie naprężenia.
