Summary: This study investigated the energy absorption capability and crashworthiness performance of Al6063-T4/T6 aluminum alloy square tubes under axial crushing through experimental methods. The use of PVC foam and polyurethane springs as reinforcement materials enhanced the energy absorption value. A novel pre-deformation process was applied to the tube inner surfaces to increase the strength. The experiment revealed that foam filling enhanced the energy absorbed more than wall-crushing, but wall-crushed tubes offered higher specific energy absorption in the T6 temper. The use of polyurethane springs significantly contributed to the crashworthiness performance compared to other samples.

Summary: This document reviews recent research on the mechanical properties of 6xxx series aluminium alloys and the crashworthiness of tubes made of these alloys. The review focuses on the material response at high strain rates and the structural response under quasi-static and dynamic loadings. It also discusses the effects of processing routes and heat treatments on the dynamic behavior of the alloys, as well as the correlation between material response and microstructural features.

Summary: This study investigates the mechanical performance of multi-cell thin-walled tubes with small aspect ratio and diameter thickness ratio and the same weight through theoretical, numerical, and experimental research. Experimental tests were conducted under static and dynamic axial loading using a lightweight device impact test. The results showed that the dynamic amplification factor (DAF) for multi-cell tubes can be ignored at impact velocities below 50 m/s. Multi-cell partitioning improves energy absorption and reduces the increment of dynamic axial loads in thin-walled structures. The numerical model indicates that dynamic axial impact leads to strain hardening of the matrix material, resulting in increased force.

Summary: This study investigates a novel crash box composed of an aluminum shell and a 3D-printed lattice core. The lattice structures, fabricated using carbon fiber reinforced polyamide 6 composites, achieved good lightweight and energy absorption characteristics. The kagome lattice structure demonstrated the highest specific energy absorption values through numerical analysis. A multi-objective optimization strategy was utilized to establish the optimal design model for the crash box, resulting in improved energy absorption with mass reduction using the non-dominated sorting genetic algorithm (NSGA-II).

Summary: The application of foam and honeycomb materials in energy absorbing devices was studied, and the crashworthiness of different filling structures was compared and analyzed through simulation models and experiments. The results show that both foam-filled and honeycomb-filled thin-walled structures can improve energy absorption efficiency, but the filling styles have an impact on their mechanical properties.

Summary: This paper investigates the crashworthiness performance of square pipes with induced holes. Taguchi technique has been adapted to determine the optimal crashworthiness parameters. The results indicate that crosshead speed and hole diameter have the highest influence on the absorbed energy, while the number and distribution of holes have the highest influence on the initial peak force.

Summary: This paper proposes a novel design of foam-filled crash boxes to enhance the energy absorption and protection capability. The study finds that partial filling design reduces material usage and increases specific energy absorption. An improved optimization strategy is proposed by considering material utilization and deformation stability. Experimental validation confirms the effectiveness of this method.

Summary: This study proposed a new thin-walled square tube structure filled with hollow aluminum metal spheres to improve its crashworthiness. Experimental and numerical simulation results showed that filling hollow spheres can change the deformation mode of the thin-walled square tube and increase its load-bearing capacity. The wall thickness, size, and stacking modes of the hollow spheres have significant impacts on the performance of the thin-walled square tube.

Summary: This study investigates the crashworthiness behavior of square aluminum thin-walled tubes subjected to axial and oblique impact loading. It examines the effects of crushing angle and initial contact between impactor and tube on plastic collapse initiation and energy absorption capacity. The results show that a 5 degrees oblique cornered crushing yields the highest energy absorption, while an initial contact-in-corner case exhibits higher energy absorption compared to axial and edged oblique loading.

Summary: A finite element axisymmetric model was developed to study the energy absorption capacity of thin Aluminum plates in terms of ballistic limit. The study found that plastic work and friction dissipate the impact energy, while projectile radius and plate thickness have a significant influence on perforation energy. The ballistic limit shows a non-linear relation with plate thickness to projectile diameter ratio.

Summary: The study investigated the effects of heat treatment on the microstructure and mechanical properties of Al-Mg-Si alloys using a Phase-Field modeling approach. It focused on recrystallization and grain growth mechanisms, as well as the calculation of yield strength and hardness after different ageing treatments. The results showed that the pinning force of secondary particles led to a slight decrease in final grain radius, and different ageing temperatures had an impact on ageing conditions for distinct ternary systems.
