Abstract.Problem of mechanical damage of corn kernels is serious in harvest and storing process. This study focuses on determining the properties of corn kernels with different geometric shape under various compression case. Three geometric shapes (pyramidal, rectangular and round) and three contact orientations of the kernel (X - axis, Y - axis and Z - axis) were consider in the experimental measurement at loading rates of 5mm·min-1. The maximum stress of pyramidal (358.98 Mpa), rectangular (1208.5 Mpa) and round (715.13 Mpa) of corn kernel appeared in Z - axis, Y - axis and Z - axis, respectively. Anti - pressing competence of various geometric shapes of corn seeds was different under same placing manners. Finite Element Method (FEM) - based explicit dynamics simulation was utilized to investigate the distribution of stress of kernels in the 3 loading directions, it could be known that the maximum stress was easy to emerge and expand to big – flat in Y – axis. The simulation results were consistent with the results of experiment. This indicates that the FEM model developed is an important tool in the study of mechanical behaviour of corn kernels and it can provide valuable information for optimising and designing of process machines.
