I. COURSE OVERVIEW:
The finite element analysis (FEA) is a numerical method widely used for modeling and analyzing structures. This
course introduces the mathematical modeling concepts of the Finite Element Method for solving structural, thermal
and dynamics problems that are too complicated to be solved by analytical methods.

II. COURSE OBJECTIVES:


The student will try to learn:
I The basic concepts of Finite Element methods and its applications to complexengineering problems.
II The characteristics and selection of different finite elements used in finite elementmethods.
III The equilibrium equations and stress-strain relations for different boundary conditions encountered in
structural and heat transfer continuum problems.
IV The application of the FEM technique to dynamic problems and validate the solutions through
simulation software for real time applications.

III. COURSE OUTCOMES:


After successful completion of the course, students should be able to:
CO 1 Choose discretization concepts and shape functions of structuralmembers for computing Apply
displacements and stresses of the aircraft components.
CO 2 Utilize the shape functions of truss and beam elements for obtaining stiffness Apply
matrix and load vector to compute nodal displacement, stresses.
CO 3 Identify the required discreet models of constant strain triangle element for Apply
estimating displacement and stress under load conditions.
CO 4 Make use of axi-symmetric modeling concepts to solids of revolution for stress Apply
approximation
CO 5 Apply numerical techniques of heat transfer problems to compute the temperature Apply
gradients under various thermal boundary conditions
CO 6 Develop the governing equations for the dynamic systems to estimate circular Apply
frequency and mode shapes, in correlation with modern tools
