Summary: Honeycomb structure, known for its light weight, high stiffness and good energy absorption characteristics, is often used in anti-collision structures. However, the equivalent model of honeycomb structure is relatively rare. To simplify mechanical analysis, a mass-spring-damper system model is proposed to describe the displacement and energy absorption of honeycomb structures. This study focuses on the hexagonal honeycomb structure as an example and validates the proposed equivalent theory through numerical simulation methods.

Summary: Two new types of hierarchical multi-cell hexagonal tubes were constructed and studied for their crashworthiness. The proposed tubes have smaller peak crushing force (PCF) compared to single hexagonal tubes with the same mass, indicating their ability to minimize sudden injury. The mean crushing force (MCF), energy absorption (EA), and specific energy absorption (SEA) of the proposed tubes increase with wall thickness and hierarchical order. The SEA of the 3rd order is over 200% of that of single hexagonal tubes with the same mass. The second type of hierarchical tubes with relatively uniformly distributed hierarchical cells exhibit slightly higher SEA than the first type with cells along the edges. The theoretical model for the first type of hierarchical tubes was further developed and validated, showing good agreement with numerical simulation.

Summary: This study investigated the progressive collapse behaviors and mechanisms of 3D printed thin-walled composite structures under quasi-static compression and dynamic impact conditions. It was found that the structures exhibited stable plastic deformation under quasi-static compression, while they showed brittle crack-to-fracture collapse under low-velocity impact. The collapse mechanisms involved bending deformation, membrane deformation, micro fiber breakage, fiber-matrix debonding, and matrix cracks. The hexagonal structures made with carbon fiber-reinforced material exhibited the best energy absorption performance.

Summary: This study investigates the effects of fibre concentration on the mechanical response of welded glass-fibre-reinforced polypropylene (GF-PP). Experimental observations reveal a significant reduction in weld ratio, up to 60%, indicating a decreased strength compared to the bulk material. Increasing fibre content in the welded material results in a decrease in stress at break and strain at the maximum stress. The use of DIC technique and X-ray microtomography further confirms the localized strain amplification in the welded zone due to the significant increase in fibre density.
