Experiment and simulation for the crushing of tailor rolled tubes with various geometric parameters
TL;DR: In this article, the effect of axially varied thickness and lengths on the energy absorption performance of TRTs was investigated, and it was concluded that more energy can be absorbed for TRTs when choosing more edge numbers of the polygonal cross-sections.
Journal ArticleDOI
Some comments on the energy-absorbing effectiveness factor
TL;DR: In this article, the authors discuss the energy absorbing effectiveness factor, which provides a ratio between the energy absorbed in a structural system with the total potentially available elastic and plastic strategies.

The effect of different layouts in internal and external stiffeners on the energy absorption of thin-walled structures with square sections
A. Alavi Nia,Ali Akhavan Attar +1 more
TL;DR: In this article, the authors examined the energy absorption and the mechanical behavior of thin-walled aluminum structures with square section, which are connected to the structural wall by either internal or external stiffeners and then exposed to axial quasi-static loading.

Crashworthiness optimization of cylindrical negative Poisson’s ratio structures with inner liner tubes
TL;DR: In this paper, a novel structure with enhanced energy absorption is proposed by introducing thin-walled tube as the inner liner tube of the cylindrical structures with negative Poisson's ratio (C-NPR), and the parametric analysis of the geometric parameters on the crashworthiness performance of C-NPR-IT structures are performed with finite element method.

Compressive and flexural properties of the novel lightweight tailored bio-inspired structures
TL;DR: In this article , the effect of strut thickness, shape, loading direction and functional grading on compressive behavior of the bird's feather-inspired structures was studied. But the results showed that the structural response of the bio-inspired structure is similar to stretch-dominated structures.

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.
