Plastic mechanism analysis of unstiffened steel I-section beams strengthened with CFRP under 3-point bending
TL;DR: In this paper, the authors presented experiments and theoretical analysis of 16 steel I-section beams strengthened using externally bonded CFRP under quasi-static large deformation 3-point bending, where CFRP plates were added either to the tension flange or both compression and tension flanges or even to the whole section including the web.

A parametric study on extrusion geometry and blade quantity during axial cutting deformation of circular AA6061-T6 extrusions under impact and quasi-static loading
TL;DR: In this paper, a parametric study on axial cutting deformation of circular AA6061-T6 extrusions was completed under both dynamic and quasi-static loading conditions.

A crushing analysis and multi-objective optimization of thin-walled five-cell structures
TL;DR: In this paper, two types of inner cellularization geometry in the thin-walled cylinders derived from previous studies on this area of subject were proposed to increase the specific energy absorption, reduce the peak energy, and improve crushing.
Journal ArticleDOI
Multi-objective robust optimization of foam-filled bionic thin-walled structures
TL;DR: In this article, a foam-filled bionic thin-walled structure (FBTS) was investigated using the software LS-DYNA in order to further improve the crashworthiness of the BTS, and the FBTS was optimized by a multi-objective deterministic optimization method.

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.
