COURSE DESCRIPTION Mechanics of materials
is a branch of applied mechanics that deals with the behavior of solid bodies subjected to various types of loading. The solid bodies considered include:
Bars with axial loads
Shafts in torsion
Beams in bending
Columns in compression
Other names for this field of study are
Strength of materials
Mechanics of deformable bodies
The principal objective of mechanics of materials is to determine the stresses, strains, and displacements in structures.
Study of mechanics of materials will provide the future engineer with the means of analyzing and designing various load bearing structures.
Both the analysis and design of a given structure involve the determination of stresses and deformations.
Engineering structures and machines, such as airplanes, automobiles, bridges, spacecraft, buildings, electric generators, gas turbines, and so forth, are usually formed by connecting various parts or members.
In most structures or machines, the primary function of a member is to support or transfer external forces (loads) that act on it, without failing.
Failure of a member may occur when it is loaded beyond its capacity to resist fracture, general yielding, excessive deflection, or instability .
These types of failure depend on the nature of the load and the type of member.
In elementary mechanics of materials, members subjected to axial loads, bending, moments, and torsional forces are studied.
