Catalog Description:
Fundamental concepts and elementary elasticity. Review of failure theories. Nonsymmetrical bending of beams. Torsion of noncircular long prisms. Elastic stability and buckling
of columns. Selected topics among energy
methods, limit analysis, beam-columns, thermal
stresses and residual stresses.
Course Objectives:
The aim of this course is to expand the
background of mechanical designers or analysts
with respect to understanding the internal behaviour
of mechanical elements under the action
of applied loads. The first course
in the theory of strength of materials should be considered only as an initial framework for the
study of stress analysis. In this
course the fundamental aspects of theory of strength of materials in terms of the mathematical level of that of a junior to senior
undergraduate student in engineering are covered. Practical stress-analysis problems and a sort of collection of known classical problems in strength of materials complete with solutions and analytical methods are included.
