 Synopsis:

Fundamentals of the theory of elasticity: stress and strain of straight beams subjected to bending and free torsion, ultimate plastic capacity of a member in bending, critical loads and buckling lengths of straight compression members. Basic assumptions, quantities, and equations describing the stress and strain state in 3D continuum, plates and walls.

 Study Objective:

Students will be able to solve the stress and strain of straight beams subjected to tension or compression, bending and free torsion, determine the ultimate plastic capacity of a member in bending, and determine the critical loads and buckling lengths of straight compression members. They will learn about the basic assumptions, quantities, and equations describing the stress and strain state in 3D continuum, plates and walls.
