Investigation of Functionality of Vehicle Crumple Zones Recovered after a Traffic Accident
TL;DR: In this paper , the authors designed numerical models allowing for forecasting of the longitudinal member and other structural elements of the vehicle in case of collision with an obstacle, and the methodology was designed to forecast the amount of energy absorbed by the thinwalled sections used in the vehicle safety cage and the course of deformation under impact loads that caused stability loss.
Experimental and Theoretical Investigation of Impact Dynamic
Hani Aziz Ameen,Ahlam Abd +1 more
TL;DR: In this paper, the authors studied the behavior of cylindrical shells under low velocity axial impact (3.8 theoretical) and showed that when the velocity of impact increases, the valuations of the dynamic crushing stress for elastoplastic collapse deformation, a tube initiall y goes through elastic deformation and then plastic deformation occurs, after that the tube goes through plastic collapse.

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.
