|Abaqus;[数]有限元分析
有限元分析(Finite Element Analysis, FEA)是一种基于数学建模的数值计算方法,用于求解复杂工程问题中的物理场分布和结构行为。其核心思想是将连续的几何体离散化为有限数量的小单元(即“有限元”),通过单元间节点的相互作用建立方程组,模拟实际工况下的力学、热学或电磁学响应。
离散化与插值函数
通过将连续体分割为三角形、四边形或四面体等形状的网格单元,每个单元内部用多项式函数近似真实物理量(如位移或温度),例如二维问题中常用拉格朗日插值函数: $$ u(x,y) = sum_{i=1}^n N_i(x,y)u_i $$ 其中$N_i$为形函数,$u_i$为节点值。该方法最早由美国国家航空航天局(NASA)在1960年代应用于航天器结构分析。
多物理场耦合能力
现代FEA可处理固体力学中的应力应变、流体动力学中的湍流,以及热电耦合等复杂现象。例如在汽车工业中,德国汽车工业协会(VDA)标准要求使用FEA验证碰撞安全性。
美国机械工程师协会(ASME)发布的《Boiler and Pressure Vessel Code》第Ⅲ卷明确将FEA列为核设备强度验证的法定方法。英国标准协会(BSI)的BS EN 1993-1-5也规定了钢结构屈曲分析的有限元实施规范。
