ABSTRACT
The present paper focuses on the compression characteristics of granular wheat stored in silos. The confined uniaxial compression tests of wheat were performed to investigate the compression behaviour of granular wheat. The effects of different loading paths and different maximum loading levels on the compression index and elastic moduli were analysed. The compression curves for each specimen were obtained from the test results. It was observed that nearly 80% of the total deformation occurred in the virgin loading stage. The compression index and elastic moduli were determined, which indicates that both the parameter compression index and elastic moduli correlate with the loading path.
