摘要
具有开孔结构的网状多孔材料是一种优秀的工程材料,孔率是此类材料的一个最为基本的易测参量,而拉压行为是工程材料最为基本的力学性能。找出多孔材料基本力学性能与其孔率的关系,无疑可以为其性能调控提供很大的便利。通过分析该类多孔材料的八面体结构模型,进一步演化出网状多孔复合材料在压缩条件下的力学分析模型。从该分析模型出发,推演得出了该类材料在压缩时的安全承载和整体承载强度等力学关系。在这些力学关系中,孔率参数展示了其重要的作用。
The porous material with reticular structure is an excellent engineering material.The porosity is the most basic and easily measured parameter for such porous materials,and the tensile and compressive behavior is the most fundamental mechanical property for engineering materials.Finding out the relation between the fundamental mechanical properties and the porosity for porous materials can undoubtedly provide great convenience for the performance control.In this paper,the octahedral structure model of porous material was used to further evolve the mechanical analysis model for reticular porous composite materials under compressive loading.Based on this analysis model,the mechanical relations were deduced for such composite materials,including the safe loading condition and the overall strength under compression.In these mechanical relations,the porosity parameter shows its important role.
