FEA (Finite Element Analysis)
Finite element analysis (FEA) is the use of calculations, models and simulations to predict and understand how an object might behave under various physical conditions. Engineers use FEA to find vulnerabilities in their design prototypes.
FEA uses the finite element method (FEM), a numerical technique that cuts a structural object into many pieces, or elements, and then reconnects the elements at points called nodes. The FEM creates a set of algebraic equations which engineers, developers and other designers can use to perform finite element analysis.
Using finite element analysis can reduce the number of physical prototypes created and experiments performed while also optimizing all components during the design phase.
The slide show below shows the FEA results from subjecting mechanical and structural components to loads.
