title: The Calculations and Simulation Testing on the Elastic Modulus of Wheat.
abstract: The elastic modulus (E) of wheat is not only an important parameter in mechanical property of wheat grain, but also is one of the most important parameter for the materials in the analysis three-dimensional modeling of wheat. In this study, the relationship between load-deformation properties of the three different moisture contents wheat grains determined by TA-XT2i texturometer and pressures in simulated analyzed using a three-dimensional model of wheat was investigated. The elastic modulus was calculated by the results of the load deformation under the pressure, and verified and amended using the three-dimensional model. The results showed that the elastic modulus range for wheat was from 37 to 75 MPa, while the moisture content of wheat rose from 10 to 20 %. The difference in compressive deformation between the reality and the model was <5 %.
