Mechanics Of Materials

ABOUT THE COURSE:
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.

INTENDED AUDIENCE: NIL

PRE-REQUISITES: Engineering Mechanics, Basic Calculus

INDUSTRY SUPPORT: NIL

CORE OR ELECTIVE: Core

UG or PG COURSE: UG

COURSE INSTRUCTOR:

Saravanan U is an associate professor in the department of civil engineering at IIT Madras. He regularly teaches this mechanics of materials course to undergraduate students in their third semester. He has authored a NPTEL web course on advanced solid mechanics. He is passionate about students learning solid mechanics in the correct way. The instructor’s research interest is in mechanics of deformable solids in which he has published more than 30 international peer reviewed journal articles.
