Role of multi-layer pyramidal truss cores as an inner material of energy absorbing structures
TL;DR: In this article, the feasibility of multi-layered pyramidal truss structures as a filler material of energy absorbing tubes was investigated and the results indicated that the energy absorption capability of the tube with the filling exceeds the simple sum of that of tube and that of the filler.

Material characterization of local strain-induced α’-martensitic reinforcements
TL;DR: In this article, the material characterization of local strain-induced reinforcements in sheet metal has been studied for different states of stress according to Nakajima tests and the developed Forming Curves (FC) enable the determination of varied failure areas and the material behavior of reinforced and original steel including bulge height.

Progressive axial crushing behaviour of Al6061-T6 alloy tubes with geometrical modifications under impact loading
S. Bhutada,Manmohan Dass Goel +1 more
TL;DR: In this article , the authors used the ABAQUS/Explicit® package to simulate the model under impact loading condition and found that a moderate weight reduction of tube can significantly affect the crushing characteristics of tube.

Analysis of bow crushing in ship collision
TL;DR: In this paper, a structural model is developed by identifying localized zones of plastic deformations from photographs of damaged ships and then, the contributions of the membrane and bending resistance are assessed and a simple computational model was developed.

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.
