Progressive collapse of foam-filled conical frustum using kinematically admissible mechanism
S.A. Meguid,F. Yang,P. Verberne +2 more
TL;DR: In this article, a kinematically admissible mechanism for the progressive collapse of a foam-filled and unfilled circular frustum is presented, taking into account the plastic strain and circumferential strain energy dissipation during collapse.

The Macro Element Approach in Crash Calculations
TL;DR: This chapter presents basic concepts of a consistent and mathematically tractable method of calculating large shape distortions in shells subjected to crash loading and considers consideration of local deforming regions with floating rather then fixed boundaries with stringent conditions of kinematic continuity at the boundary between neighboring elements.

Proactive regulation of axial crushing behavior of thin-walled circular tube by gradient grooves
TL;DR: Based on the plastic hinge formation process, a sectionalized theoretical model is established to predict the quadratic upward trend of crushing force of a gradient grooved tube (GGT) designed for high temperature gas cooled reactor (HTR) as discussed by the authors.

Dynamic axial compression of aluminum hollow tubes with hat cross-section and buckling initiator using inertia force during impact
TL;DR: In this paper, the first plastic buckling lobe was demonstrated, where the inertia force in the early stage of impact was exploited, and the method used the solid block attached to the structural wall causing the wall bending force.

Energy absorption of aluminum alloy thin-walled tubes under axial impact
TL;DR: In this paper, the axial crushing of square and multicorner thin-walled tubes with the same cross-sectional perimeter was simulated with different number and size of concave corners on the cross-section.

Dynamic axial crushing of square tubes
W. Abramowicz,Norman Jones +1 more
TL;DR: In this paper, the axial progressive crushing of square box columns using a kinematically admissible method of analysis was investigated and four deformation modes which govern the behaviour for different ranges of the parameter c/h.

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 quasi-static crumpling of thin-walled circular cylinders and frusta under axial compression
A.G Mamalis,W Johnson +1 more
TL;DR: In this paper, thin-walled circular cylinders and truncated circular cones of aluminium alloy were subjected to axial static loading and their initial axial length and the outside diameter of cylinders and frusta were kept constant whilst their wall thickness was varied.

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.
