Analysis of finite element method on mechanical properties of wheat kernel.

The scattered cases of wheat kernels were examined for ensuring the direction of wheat kernels. Above 50% kernels of wheat were back up and about 43% were sides up. Finite element method was performed to simulate stress distributions inside a wheat kernel during storage. The distributions of fixture, force, tangential, deformation, and displacement were mapped and analyzed. The grid for wheat consisted of the model consists of 1620 nodes and 937 triangular elements. The stress of sides was about 3 times higher than the bottom. Figure 6 illustrated the displacements of wheat were distinct in different status in storage. The displacement on side status was greater than on bottom of wheat.
