Collapsible impact energy absorbers: an overview
TL;DR: In this article, the common shapes of collapsible energy absorbers and different modes of deformation of the most common ones are reviewed, such as axial crushing, lateral indentation, lateral flattening, inversion and splitting, while noncollapsible systems such as lead extrusions or tube expansions are considered to be beyond the scope of this review.

High strain rate compressive behaviour of aluminium alloy foams
Vikram Deshpande,Norman A. Fleck +1 more
TL;DR: The high strain rate compressive behavior of two cellular aluminium alloys (Alulight and Duocel) has been investigated using the split Hopkinson pressure bar and direct impact tests.
Journal ArticleDOI
Dynamic compressive strength properties of aluminium foams. Part II—‘shock’ theory and comparison with experimental data and numerical models
TL;DR: In this article, one-dimensional "steady-shock" models based on a rate-independent, rigid, perfectly-plastic, locking (rp-p-l) idealisation of the quasi-static stress-strain curves for aluminium foams are proposed for two different impact scenarios to provide a first-order understanding of the dynamic compaction process.

Thermodynamically stable whilst kinetically labile coordination bonds lead to strong and tough self-healing polymers
Jian-Cheng Lai,Xiao-Yong Jia,Da-Peng Wang,Yibing Deng,Peng Zheng,Cheng-Hui Li,Jing-Lin Zuo,Zhenan Bao +7 more
TL;DR: Control experiments showed that the optimal combination of its bond strength and bond dynamics is responsible for the material’s mechanical toughness and self-healing property.

TL;DR: In this paper, a simple shock model based upon a rate-independent, rigid, perfectly-plastic, locking (r-p-p l) idealisation of the stress-strain curves for wood is proposed to provide a first order understanding of the dynamic response.

Axial crush of metallic honeycombs
Enboa Wu,Wu-Shung Jiang +1 more
TL;DR: In this paper, experimental results for six types of honeycomb cellular structures under quasi-static and impact loads applied in the axial direction are reported, and an increase of up to 74% of the crush strength was observed when the specimens which were loaded dynamically were compared with those loaded under the quasistatic conditions and the increase was found to be proportional to the initial striking velocity of the projectile.

Structural Crashworthiness and Failure
Norman Jones,Tomasz Wierzbicki +1 more
TL;DR: In this article, failure in ductile material using finite element methods and modelling the process of failure in structures are discussed. But the authors focus on the inelastic rupture of ductile metal beams subjected to large dynamic loads, strain localisation and fracture in metal sheets and thin walled structures; impact on metal tubes; indentation and perforation; composite strength and energy adsorption as an aspect of structural crash resistance; crash response of composite structures; dynamic compression of cellular structures and materials; elastic effects in the dynamic plastic response of structure; impact performance of aluminium structures

TL;DR: In this paper, an experimental study of the impact of blunt strikers with a diameter of 1.85 in. (47mm) on both bare honeycombs and sandwich plates with honeycomb cores is described.
