FEA – Finite Element Analysis

Finite Element Analysis, which is the application of the Finite Element Method, is a mathematical technique used to determine approximate solutions for partial differential equations (PDE).

With reference to machine design it provides a structural analysis technique dependent upon a set of physical laws and mathematics used to study and predict structural behavior.
 

Structural analysis reviews engineering artifacts whose integrity is judged fundamentally upon their ability to withstand loads. In its application to mechanical design it draws in the disciplines of mechanics, dynamics, and failure theory.

Finite Element Analysis is primarily concerned with obtaining the computation of deformations, internal forces, and stresses, and of providing a method of proving design soundness without the need of directly building and testing it.
