|Abaqus;[數]有限元分析
有限元分析(Finite Element Analysis, FEA)是一種基于數學建模的數值計算方法,用于求解複雜工程問題中的物理場分布和結構行為。其核心思想是将連續的幾何體離散化為有限數量的小單元(即“有限元”),通過單元間節點的相互作用建立方程組,模拟實際工況下的力學、熱學或電磁學響應。
離散化與插值函數
通過将連續體分割為三角形、四邊形或四面體等形狀的網格單元,每個單元内部用多項式函數近似真實物理量(如位移或溫度),例如二維問題中常用拉格朗日插值函數: $$ u(x,y) = sum_{i=1}^n N_i(x,y)u_i $$ 其中$N_i$為形函數,$u_i$為節點值。該方法最早由美國國家航空航天局(NASA)在1960年代應用于航天器結構分析。
多物理場耦合能力
現代FEA可處理固體力學中的應力應變、流體動力學中的湍流,以及熱電耦合等複雜現象。例如在汽車工業中,德國汽車工業協會(VDA)标準要求使用FEA驗證碰撞安全性。
美國機械工程師協會(ASME)發布的《Boiler and Pressure Vessel Code》第Ⅲ卷明确将FEA列為核設備強度驗證的法定方法。英國标準協會(BSI)的BS EN 1993-1-5也規定了鋼結構屈曲分析的有限元實施規範。

有限元分析(Finite Element Analysis,FEA)是一種基于數學和計算機技術的工程分析方法,用于求解複雜物理系統的近似解。其核心思想是将連續的複雜結構離散化為有限數量的小單元(如三角形、四邊形或立方體),通過建立單元間的數學關系來模拟整體行為。以下是詳細解釋:
基本方程可簡化為: $$ mathbf{K}mathbf{u} = mathbf{F} $$ 其中 $mathbf{K}$ 為剛度矩陣,$mathbf{u}$ 為節點位移向量,$mathbf{F}$ 為載荷向量。
