Plane stress state,the so-called disks. First, all the necessary basic equations describing the plane stress state are summarized. After that, the topic of stress transformation is discussed. It turns out that extremal normal stresses, the so-called principal stresses, occur under certain orientations of the coordinat

Beams,t derived for an arbitrary coordinate system, where different recurring area integrals are also introduced. Special attention is paid to the so-called moments of inertia and the so-called deviation moment. The two cross″?=sectional normalizations, i.e. the reference of the considerations to the cent

Energy methods,ter a?brief introduction to the concepts of work and energy, strain energy and complementary strain energy are introduced for bars and beams. Then, the principle of work and energy is used to determine deformations in beam and bar structures. Another essential aspect of energy methods in structural

Buckling of bars,d the determination of critical loads (i.e. the load under which a?previously straight member changes to a?deflected position), as necessary for the understanding of this chapter, we discuss the determination of buckling loads of bars under compressive load under various boundary conditions.
