In these slides we will discuss the chapter no 4 of mechanics of material which is related to the concepts of "Pure Bending". The aim of teaching this chapter are

Introduce students to bending behavior
Define the deformations, strains, and normal stresses in beams subject
to pure bending
Describe the behavior of composite beams made of more than one
material
Review stress concentrations and how they are included in the design
of beams
Study plastic deformations to determine how to evaluate beams made
of Elastoplast materials
Analyze members subject to eccentric axial loading, involving both
axial stresses and bending stresses
Review beams subject to unsymmetrical bending, i.e., where bending
does not occur in a plane of symmetry
Study bending of curved members
