This study analyses the energy absorption and stiffness behaviour of 3D-printed supportless, closed-cell lattice structures. In this respect, their more widespread application has been limited by the complexity of their collapse behavior. Synergistic Energy Absorption Mechanisms of Architected Liquid Crystal ... In this paper, polyvinyl chloride (PVC) coarse aggregate with different mixing contents is used to solve the problems of plastic pollution, low energy absorption capacity and poor damage integrity, which provides an important reference for PVC plastic concrete used in the initial support structures of highway tunnels and coal mine roadway. Fluorine substitution was applied to the donor and acceptor segments of block copolymers to understand the impact of molecular structure on photovoltaic block copolymers and explore efficient materials for single-component organic solar cells (SCOSCs). Retracted: Mechanical Properties and Energy Absorption ... - Wiley Either the energy is absorbed directly by the aircraft structure by ductile deformation through the selection of appropriate skin materials (e.g. Overall, this study has shown that the energy absorption capacity of thin-walled structures can be significantly enhanced with the use of carbon nano foams. PDF Effect of Internal Microstructure Distribution on Quasi-Static ... This thesis presents a new, simple and precise nano-scale fabrication technique: by using femtosecond laser irradiation to develop novel nanofibrous structures. More recently, the attention of academia and industry has turned to the multifunctional performance of cellular materials and structures. PDF ADVENGMAT Vol. 18 - No. 11 November, 2016 The unit cell design is bioinspired by the sea urchin morphology having organism-level biomimicry. In recent years, the problem of buffer energy absorption within a narrow space has arisen as an important topic of interest in the aerospace industry. lies in the range in between 0.5-2.1 gm/cm3. 12.12 (a). Zhao et al. nature, bio-inspired structures have been proved to exhibit a significant improvement over conventional structures in energy absorption capacity. It is defined as: = ∫ (1) To relate how much energy a structure can absorb to it mass, specific energy absorption is obtained.
