摘要
木材作为一种天然的生物质材料,受自身解剖特征、各向异性的结构特点及对外界温湿度响应不同等特征的影响,导致受力过程中的力学行为异常复杂,常规测试方法难以进行全面有效的表征.随着计算机技术的进步,有限元可以根据材料特性有效模拟、分析材料在受力过程中的力学效应和演变情况,目前在木材及木质复合材料领域得到广泛应用.基于木材生物质高分子材料的特性,阐述了有限元分析在生物特性对木质材料受力力学行为、木材断裂行为及破坏模式方面的应用,论述了有限元分析方法在木制品单元材料、构件、连接方式及属性对木制品受力状态和演变过程的研究现状.最后,结合木质材料及制品特征分析了有限元在木质材料受力分析中的发展前景.
Abstract
As one kind of biomass material,the mechanical behavior of wood material is complex and difficult to con-duct comprehensive and effective simulation due to its own organization,structure,anisotropy and external temperature and humidity.As computer technology advances,finite element method has been widely applied in mechanical properties analysis of wood and wood composite materials.Centered around the properties of biomass and polymers of wood,this paper elaborated the application of finite element analysis in effect of biological properties on wood stress station,wood fracture behavior and the failure mode,the research status of finite element analysis in effect of cell material,connection mode and wood stress station.Finally,combined with wood materials and the product characteristic,the development prospects of the finite element in wood loading material stress analysis was expounded.
