【摘要】 从苎麻茎秆结构组成及现有剥离方式两方面定性地分析了苎麻茎秆组分韧皮与木质部的力学性能,两者机械性能存在较大差异;简述了在线弹性条件下农业固体物料本构关系建立的方法;按照线性复合材料的力学分析理论,假设茎秆及其组分韧皮与木质部为横观各向同性材料,探讨了建立其相应本构关系的过程和苎麻茎秆力学分析模型的方法。更多还原

【Abstract】 Analyzing qualitatively mechanics properties on bast fibre and xylem of ramie stems ,According to structural composition and ways of current peeling Ramie. it proved that the differences of mechanical behavior between bast fibre and xylem are obvious .On condition that physical properties of agricultural solid materials belong to properties of linear elasticity, Stating simple methods of establishing their constitutive relations. By analytical theory of mechanics on linear composite materials , Assuming that ramie Stems, bast fibre and xylem belong to transversely isotropic materials . discussing the process of building their corresponding constitutive relations and analytical methods of mechanics model on Ramie stems.更多还原
