Impact responses of steel–concrete–steel sandwich panels with interlocked angle connectors: Experimental and numerical studies
TL;DR: In this paper , the impact responses of a steel-concrete-steel sandwich composite panel with novel interlocked angle connectors (SCSP-IACs) were performed via a hemispherical hammer.
Development of material models to predict the crashworthiness of tubes
TL;DR: In this paper, the authors present a method to predict the crashworthiness of structural components using material modes and validate the crushing of a square tube model in Abaqus, which is used to construct a simple, physically realistic constitutive model and new test methods for predicting the material behaviour at high strain rates using low test speeds.

Numerical Study of the Influence of Internal Blast on the Earth Covered Composite Arch
Jindrich Fornůsek,Jan Zatloukal +1 more
TL;DR: In this article, a numerical study of an earth covered composite arch subjected to internal blast load equaled to 6,25 tons of TNT was carried out and it was found that the presence of the corrugated sheet anchored to the arch can reduce 40 % of arch damage compared to the unprotected arch.

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.
