Description:
Solid mechanics is the branch of mechanics that concerns the behavior, especially deformation, of solid matter under external actions. This course is the most basic one that a mechanical engineer ought to do. The mechanics studied in high school is generally for rigid bodies. In this course, one studies the mechanics of deformable bodies. This course gives a basic introduction to the concepts of stress, strain, axial force, shear force, bending moment, bending and torsion for elastic bodies.
The branch of solid mechanics is a part of a larger branch called continuum mechanics: (image courtesy: Wikiimages)
Course Contents:
 Fundamentals of mechanics of deformable solids – Introduction, analysis of axial and shear loaded components.
 Castigliano’s theorem.
 Beams – shear force and bending moment diagrams.
 Stress, strain, and their relationships.
 Thermal stress, fatigue and creep. Mohr circle.
 Stresses in beams.
 Torsion.
 Thick cylinders and rotating discs.
Motivation:
 Mechanics of solids has direct applications in product development. In any industrial or research based application, whenever one is required to develop a product or even a small machine part design of any component should be done so that the maximum stress is minimized. For this, one must have a clear understanding of the stresses and strains on the body. This course will develop the basics of calculating the stresses/ strains for different types of bodies and forces.
 Any future courses which need this course as an official or unofficial prerequisite –
 ME 202 Strength of Materials
 ME 423 Machine Design
 ME 601 Stress Analysis
 ME 602: Fatigue, fracture and failure analysis
 ME 616 Fracture Mechanics
 ME 734: Vibro Acoustics

While it is a good practice to refer to textbooks or video lectures besides your class notes, it is also important to remember that these sources may not be flawless. Reference material should only be used as a tool to strengthen concepts and not as a substitute for your class notes.
