FGM概念 FGM是功能梯度材料(Functionally graded materials)的英文簡稱,也被稱為梯度功能材料。功能梯度材料(FGM)是一種新型非均勻復(fù)合材料,是由性能不同的兩種或多種材料復(fù)合成組分和結(jié)構(gòu)呈現(xiàn)連續(xù)梯度變化的材料。它要求功能、性能隨內(nèi)部位置的變化而變化,以實現(xiàn)功能梯度的材料。 從本質(zhì)上來講,F(xiàn)GM是一種比較特殊的復(fù)合材料。 在自然界也有許多功能梯度材料的例子,如竹子、貝殼、骨骼等。 FGM構(gòu)建 本文采用COMSOL軟件進行FGM模型的構(gòu)建,以下表現(xiàn)三種不同形式的功能梯度材料模型: 粒徑均勻變化 雙材料擴散 變粒徑分布 建模教程 在COMSOL內(nèi)建立功能梯度材料可以采用AutoCAD模型導(dǎo)入的方式,這里用到了CAD建模插件。 插件下載: CAD 功能梯度材料(FGM)2D插件

梯度功能材料(Functionally Graded Materials, FGMs)是一種先進的復(fù)合材料,其特點是材料的組成、結(jié)構(gòu)以及孔隙率等特性在某個方向上呈現(xiàn)連續(xù)或階梯式的漸變。這種變化使得FGM的物理和化學(xué)性能在同一方向上也呈現(xiàn)出相應(yīng)的連續(xù)梯度變化。 ANSYS Workbench內(nèi)建立梯度功能材料模型可以采用CAD功能梯度材料2D插件建模后導(dǎo)入到Workbench內(nèi)。在插件內(nèi)設(shè)置模型參數(shù)后運行即可在AutoCAD內(nèi)建立梯度分布的隨機圓形模型。 在CAD內(nèi)將FGM模型構(gòu)建實體后導(dǎo)出為IGES格式文件。 將模型導(dǎo)入到Workbench內(nèi)。 可對梯度模型進行后續(xù)分析模擬。 CAD 功能梯度材料(FGM)2D插件 https://www.yqgqt.org.cn/post/1874171

FGM概念 FGM是功能梯度材料(Functionally graded materials)的英文簡稱,也被稱為梯度功能材料。功能梯度材料(FGM)是一種新型非均勻復(fù)合材料,是由性能不同的兩種或多種材料復(fù)合成組分和結(jié)構(gòu)呈現(xiàn)連續(xù)梯度變化的材料。它要求功能、性能隨內(nèi)部位置的變化而變化,以實現(xiàn)功能梯度的材料。 從本質(zhì)上來講,F(xiàn)GM是一種比較特殊的復(fù)合材料。
功能梯度材料(Functionally Graded Materials, FGM)是指化學(xué)成分或結(jié)構(gòu)在空間上按照預(yù)期設(shè)計逐漸變化以實現(xiàn)特定性能的材料[1]。其概念最早是由日本科學(xué)家在20世紀80年代提出。不同于傳統(tǒng)的復(fù)合材料,F(xiàn)GM是在兩種材料之間加入一個逐漸變化的梯度層,以此來降低內(nèi)部應(yīng)力。
