On the stability behaviour of elastic beams under internal pressure

Lena Zentner, Valter Böhm, Hartmut Witte
Scientific reception of the term "stability" stresses steady adaptation to its changing fields of application. Nevertheless, the determination of critical forces remains one of the main tasks of stability theories. We exemplify some classes of the stability loss in beams under internal pressure for the static case. Additionally, we analyse in more detail the dynamic stability of beams under internal pressure and demonstrate means to keep an equilibrium.
