作物组织结构与力学性能研究

Research on crop tissue structure and mechanical properties

传统的宏观力学性能试验方法无法解析作物的力学性能与形态结构、微观结构和化合物成分存在的内在联系。显微图像获取与处理技术和有限元分析的深度发展使多尺度方法成为了作物力学研究的新途径。作物组织结构与力学性能研究是作物多尺度力学的重要部分。本文从作物组织的形态结构及几何模型构建方法、力学模型构建与求解方法和力学性能试验方法等3个方面对作物组织多尺度结构力学的研究现状进行了综述,分析了现有的组织几何模型与力学模型构建方法和力学性能试验方法等方面存在的局限性,并对多尺度结构力学研究进行了展望。

Crop mechanical properties are intrinsically related to its morphological structure,microstructure and compound composition,and traditional macroscopic mechanical test methods cannot resolve the relationship.The development of microscopic image acquisition and processing technology and finite element simulation has led to a new approach to study on crop mechanics at multiple scales.The study of the structure and mechanical properties of crop tissue is an important part of crop mechanics at multiple scales.This paper reviewed the current status and development of research on the multi-scale structural mechanics of crop tissue from three aspects:Morphological structure and geometric model construction methods,mechanical models and its solution method,and mechanical performance experiment methods of crop tissue,and pointed out their current shortcomings from those three aspects.The prospects for conducting multi-scale structural mechanics research were also presented.
