基于压痕加载曲线的谷物籽粒硬度性能测定技术（Testing of Grain Hardness Based on Indentation Loading Curve）
谷物 籽粒 硬度 压入法 试验
2010/5/5
使用500N微机控制材料试验机，利用压痕加载曲线，进行了用针尖压入法测定谷物籽粒硬度的试验研究，测得豌豆、蚕豆、大米、绿豆、小麦、扁豆以及玉米在不同组成部位、不同含水率时的硬度值在2～75MPa范围内。研究表明，试验加载速度在0.25～2.00mm/s范围内、针尖压入深度在0.25～1.50mm范围内时对试验结果无明显影响，而针尖锥度与籽粒硬度存在定量关系。 By using the 500N m...
