| 摘 要： | 木纤维是以森林为主体的可再生、可重复利用的生物质材料,利用木纤维开发的纤维增强材料具有与环境友好、和谐等诸多优点,受到人们的广泛重视,但由于对木纤维的纳米结构缺乏足够的了解,其独特的尺寸效应、局域场效应、量子效应以及表面效应没有完全发挥。研究了基于有限元理论的生物质材料木纤维的纳米结构建模机理,应用数值技术和有限分割的方法构建了木纤维可视化力学模型。

| Abstract: | Wood fiber is forest-based renewable,reusable biomass materials and fiber-reinforced materials developed from wood fiber are environment-friendly and harmonious,having drawn the widespread attention,but because of the lack of understanding of nano structure of wood fiber,their unique size effect,local field effect,quantum effect as well as surface effect haven't been brought into full play.Finite element-based nano-structure modeling mechanism of biomass material,wood fiber is studied and numeric technology... |
