多孔结构建筑材料力学性能的有限元分析

多孔材料是一种新兴的材料,制备较易,成本较低。相对于一般连续介质材料而言,多孔材料具有比强度高、比表面积高、相对密度低、重量轻、隔音、隔热等优点。它最大的特点是具有排列规则、大小可调的孔道结构,在建筑材料中也有很多的应用。因此,对非均匀孔洞与均匀孔洞建筑材料力学性能的研究是很重要的课题。论文通过建立非均匀孔洞和均匀孔洞的有限元模型,对比分析两种模型的受力性能,更好地进行多孔建筑材料的推广和使用。

Finite Element Analysis of Mechanical Properties of Building Materials with Porous Structure

Porous material is an emerging material that is easier to prepare and less costly to prepare.Compared with the general continuous media materials,porous materials have the advantages of high specific strength,high specific surface area,low relative density,light weight,sound insulation,heat insulation and so on.It is characterized by regular arrangement and adjustable size of the pore structure,and has many applications in building materials.Therefore,it is very important to study the mechanical properties of non-uniform cavity and uniform cavity building materials.By establishing the finite element model of non-uniform cavity and uniform cavity,the paper compares and analyzes the mechanical properties of the two models,so as to promote and use the porous building materials better.
