What is Finite Element Analysis?• Finite Element Analysis (FEA) is setting up

the stress and strain equations for small pieces (elements) of a structure and then combining these equations to solve for the stresses and strains of the whole structure at once.

What is Finite Element Analysis?

More accurate but harder to understand definition:

• Finite Element Analysis (FEA) is a numerical procedure to solve the governing equations of a body through piece-wise approximations applied to the entire body.
