The document provides an overview of the Finite Element Method (FEM), highlighting its history, applications, and procedural steps. It details the method's origins in the 1940s and its evolution for solving various engineering problems by the 1970s. The summary concludes with a reference for further information on FEM.

3. Finite Element Method
• numerical method to obtain an approximate solution
to a class of boundary value problems

4. Finite Element Method
• In 1940, Alexander Hrennikoff and Richard
Courant have used some formulations –
torsion of non-circular shafts – civil and
aeronautical engineering.
• In the early years of 1970 the finite element
method was developed to solve the
problems on static and dynamic problems,
small deformation, etc.,
• ANSYS, NASTRAN, ABAQUS

5.  Equilibrium problems
 Eigen value problems
 Propagation problems

6.  Conversion of differential equation into integral form
 Discretization of the structure
 Selection of an interpolation model
 Formulation of equilibrium equations
 Post processing
