FEA is the acronym for 'finite elements analysis'. Based on the finite element method (FEM), it is a technique that makes use of computers to predict the behavior of varied types of physical systems such as deformation of solids, heat conduction, and fluid flow.

Three governing equations, plus boundary conditions such as forces and pressures, form the basis for finite element analysis: Equilibrium Equations. Strain-Displacement Relations. Constitutive Equations (Hooke's Law)

The order of element describes how many nodes are on an element edge. 1st order elements have nodes only at the corners of their edges. Higher order elements also have nodes at points along the element edges, so called mid-side nodes. They are usually only available for solid elements.

The complete set, or assemblage of elements, is known as a mesh . The process of representing a component as an assemblage of finite elements, known as discretisation, is the first of many key steps in understanding the FEM of analysis.

Adjacent elements are connected to each other AT the nodes. A node is simply a point in space, defined by its coordinates, at which DEGREES OF FREEDOM are defined. In finite element analysis a degree of freedom can take many forms, but depends on the type of analysis being performed.

General FEA formula O gives: F= K u, where K is stiffness Matrix, [K].

The finite element formulation uses a high-order bending theory such that the total strain energy includes the bending strains, transverse shear strains, and transverse normal strain.

Elements in FEA are generally grouped into 1D element, 2D element, and 3D element. They are recognised based on their shapes. For example, elements can take on the form of a straight line or curve, triangle or quadrilateral, tetrahedral and many more. The simplest element is a line made of two nodes.
