NPTEL: Mechanics Of Materials

This first course in mechanics of deformable bodies introduces the four concepts - Force, stress, strain, displacement - and the four equations that connect them, namely equilibrium equations, constitutive relation, compatibility condition and strain displacement relation.Systematic procedure to solve problems of engineering interest is outlined. In particular, force and displacement relation of structural elements subjected to uniaxial stress, bending, twisting and inflation is studied. Estimation of possible modes of failure of these structural elements and the failure load is outlined.


Week 1: Mathematical Preliminaries
Week 2: Concept of Force, Displacement and stress
Week 3: Transformation of stress and equilibrium equation
Week 4: Concept of strain
Week 5: Constitutive relation, strain energy and potential
Week 6: Displacement due to uniaxial loading, temperature and bending
Week 7: Stresses and deflection in homogeneous beams loaded about one principal axis
Week 8: Stresses and deflection in beams loaded about principal axis
Week 9: Stresses and deflection in beams not loaded about principal axis
Weel 10: Stresses and displacement due to torsion
Week 11: Thick and thin walled pressure vessels
Week 12: Failure modes

What are MOOCs?
MOOCs stand for Massive Open Online Courses. These are free online courses from universities around the world (eg. Stanford Harvard MIT) offered to anyone with an internet connection.
How do I register?
To register for a course, click on "Go to Class" button on the course page. This will take you to the providers website where you can register for the course.
How do these MOOCs or free online courses work?
MOOCs are designed for an online audience, teaching primarily through short (5-20 min.) pre recorded video lectures, that you watch on weekly schedule when convenient for you.  They also have student discussion forums, homework/assignments, and online quizzes or exams.
