Basic Steps & Phases Involved In FEA:

Steps :

Discretization
Selection of approximation of functions
Formation of elemental stiffness matrix
Formation of total stiffness matrix
Formation of element loading matrix
Formation of total loading matrix
Formation of overall equilibrium equation
Implementation of boundary condition
Calculation of unknown nodal displacements
Calculation of stresses and strains
Contd..

Phases:

Pre Processing:
Here a finite element mesh is developed to divide the given geometry into subdomains
for mathematical analysis and the material properties are applied and also the boundary
conditions.

Solution:
In this phase governing matrix equations are derived and the solution for the primary
quantities is generated.

Post-Processing:
In the last phase, checking of the validity of the solution generated , examination of the
values of primary quantities such as displacement and stresses,errors involved is carried
out.
