Geometrical Optimization of Top-Hat Structure Subject to Axial Low Velocity Impact Load Using Numerical Simulation
TL;DR: In this paper, the authors focused on analyzing the behavior of top-hat and double-hat thin-walled sections subjected to axial load by theoretical analysis and finite element method, and used the results of these models to optimize a tophat column subject to mean crushing force and sectional bending stiffness constraints by the two-step RSM-Enumeration algorithm.

Effect of elastoplastic behavior on the impact response of expanded metal tubes
TL;DR: In this article, a numerical study on the effect of the elastoplastic behavior of the material on the structural response of expanded metal tubes subjected to impact loads is presented, and the results show that the response is sensitive to changes in the orientation of the geometrical axes of the mesh.

Dynamic axial crushing of circular tubes
W. Abramowicz,Norman Jones +1 more
TL;DR: A series of axial crushing tests on steel circular cylindrical shells loaded either statically or dynamically is reported and compared with various theoretical predictions and empirical relations in this article, where a modified version of Alexander's theoretical analysis for axisymmetric, or concertina, deformations gives good agreement with the experimental results when the effective crushing distance is considered and provided that the influence of material strain rate sensitivity is retained in the dynamic crushing case.

The effective crushing distance in axially compressed thin-walled metal columns
TL;DR: In this paper, a simplified theoretical model of a compressed rigid-linearly strain hardening metal strip is studied and a closed-form solution is derived for the crushing distance of unstiffened as well as transversly stiffened box columns.
