What is Finite Element Analysis (FEA) ?
FEA is typically used to model or simulate the behavior of complex mechanical parts to external stimuli. It is most useful on complex parts or assemblies that would be very difficult or impossible to solve in a mathematically closed form manually. It is frequently used to minimize or possibly eliminate building physical prototypes for testing. FEA involves building an accurate 2D or 3D geometry model of the component to be analyzed. The model is broken up into discrete elements with nodes at their corners. Material properties are assigned for all materials used in the part. Boundary conditions are used to model physical connections to the part by setting the appropriate degrees of freedom (DOF) for all boundary nodes. Each node has up to six DOF comprised of three for translation, and three for rotation. Boundary conditions can also be used to model: dynamic, thermal, fluidic, and electrostatic connections. This part of the modeling process is done with a CAD like preprocessor to the F
FEA consists of a computer model of a material or design that is stressed and analyzed for specific results. It is used in new product design, and existing product refinement in the objective to predict structural failure. The FEA numerical solution is a mathematical formulation of a physical structural behavior, and the primary calculation is to solve the stiffness matrix. Stress analysis is probably the most common application of the finite element method. It is applied to numerous industries such as aerospace, electronics, automotive, consumer products, marine, and heavy equipment. The primary unknowns calculated in a stress analysis are displacements. Other quantities, such as strains, stresses, and reaction forces, are then derived from the displacements.

It is frequently used to minimize building physical prototypes for testing. Eliminating physical testing completely is not a good idea, that places too much faith in the analysis alone.
