Impact buckling of a thin bar
Witryna1 lip 2001 · 1.. IntroductionElastic–plastic buckling of beams under dynamic loads is an important problem in dynamics. Usually, it is assumed that the beam is instantaneously brought to the state of uniform compressive stress (the so-called uniform thrust theory, see e.g. [1]).This problem has been a subject of extensive research; the results are … Witryna11 sty 2024 · Over half of disk galaxies are barred, yet the mechanisms for bar formation and the life-time of bar buckling remain poorly understood. In simulations, a thin bar undergoes a rapid (<1 Gyr) event called "buckling," during which the inner part of the bar is asymmetrically bent out of the galaxy plane and eventually thickens, developing …
