Energy Absorption Characteristics and Optimal Welding Space of Square Hat Type Thin-walled Tube
TL;DR: In this paper, energy absorption characteristics and optimal welding space of spot-welded square hat type tube are investigated via quasi-static crush experiments and finite element (FE) analyses, and the results suggest an optimal spot welding space for each specimen width.

Plastic Collapse of Cylinders Under Constrained Conditions
Akrum Abdul-Latif,K. Nesnas +1 more
TL;DR: In this paper, a specific arrangement of two geometrically identical cylinders compressed laterally is studied under different quasi-static strain rates, and the load-deflection curves are recorded and then the energy absorbed per unit volume is determined.

Crashworthiness Optimization Design of Thin-Walled Tube Filled with Re-entrant Triangles Honeycombs
TL;DR: In this article, a reentrant triangles-filled tube (RTT) is proposed through decoupling structural stiffness and energy absorption, and the cross-section of tube with optimal stiffness is obtained with targets for maximizing axial stiffness and lateral stiffness by employing static topology optimization method.
Development of novel crash structures
TL;DR: In this article, the crash properties of carbon fiber composites were studied in detail, and novel materials were developed and characterized so that they could potentially be used for automotive crash applications.

Strengthening of thin-walled (hollow) steel sections using fibre-reinforced polymer (FRP) composites
TL;DR: In this paper, a series of experiments with a wide range of thin-walled steel section geometries where the exterior surfaces of the tube walls were strengthened with bonded carbon fibres was discussed.

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.
