Estimation of Collapse Load for Thin-Walled Rectangular Tubes Under Bending
Dai-Heng Chen,K. Masuda +1 more
TL;DR: In this article, the authors investigated the postbuckling strength of a tube web under bending and found that the collapse may also occur due to the buckling of a rectangular tube under bending, when the tube has a cross section with a large aspect ratio of web to flange b/a.

Low Velocity Impact Analyses of Prismatic Columns Using Finite Element Method
TL;DR: In this paper, the impact of prismatic columns of different cross-sections subjected to low velocity impact was numerically analyzed using FEM and the results showed that columns with equal perimeter and thickness have the highest mean crushing force and those with square cross sections have the lowest crushing forces.

Study on crashworthiness of nature-inspired functionally graded lattice metamaterials for bridge pier protection against ship collision
TL;DR: In this paper , an innovative nature-inspired functionally graded lattice filled protection structure (FGLPS) is proposed to enhance structural energy absorption characteristics under ship impact loadings, which can significantly reduce the peck impact force, prolong the impact time and play prominent protective role.
Collapse of square metal tubes in splitting and curling mode
TL;DR: In this article, a simple quasi-static kinematic model is developed which describes all the main features of the deformation process of axially splitting and curling square mild steel and aluminium tubes.

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.
