中文摘要:对农作物茎秆的力学模型、力学特性、茎秆微观结构与茎秆的力学特性关系进行了综合评述。目前对茎秆的力学性能的研究基本上还是参照工程材料的力学性能指标体系进行的,所建的力学模型还是将茎秆作为各向同性体,生物材料的复杂结构、粘弹性以及各向异性在目前的研究中没有得到很好的反映。提出了从材料科学的观点研究农作物茎秆的结构与功能特点,在建立茎秆材料模型的基础上,建立茎秆的力学模型与力学指标体系,进而建立茎秆材料的本构方程和破坏准则。

Abstract: The mechanics model, mechanical property of crop stalks, and the influence on its mechanical property by microstructure of crop stalks were overviewed. By now, the study on mechanics property of crop stalks is still on the reference of the mechanics index of engineering material, and the mechanics model is still based on taking crop stalks as isotropic material. The complex structural, viscoelasticity and anisotropic property of biological material had not been well reflected in those studies. The viewpoint presented in the paper for studying crop stalks mechanics is that studying its features of structure and function by the view of material science, establishing mechanical model and mechanical property index system based on the material model, and building up the constitutive equation and the strength criterion of crop stalks material cab.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
