Carbon fiber reinforced polymer (CFRP) and CFRP-based composite honeycomb sandwich structures are particularly sensitive to impact. The mechanical characteristics of under oblique impact studied by numerical simulation experiment. model is established, the reliability verified test. To further analyze influence structural parameters on energy absorption impact, angle, face sheet thickness wall numerically studied. results show that angle has an important effect distribution. also have peak...
Lightweight sandwich structures have been receiving significant attention. By studying and imitating the structure of biomaterials, its application in design has also found to be feasible. With inspiration from arrangement fish scales, a 3D re-entrant honeycomb was designed. In addition, stacking method is proposed. The resultant novel utilized as core order increase impact resistance under loads. created using printing. low-velocity experiments, mechanical properties with...
Due to the complexity of composite structure, analyzing material failure process carbon fiber reinforced polymers (CFRP) is fairly difficult, particularly for machining process. Peridynamic theory, a new branch solid mechanics, useful tool dealing with discontinuities. This study presents an ordinary state-based peridynamic (OSB-PD) model unidirectional CFRP in cutting In this model, angle tolerance used overcome limitation classical OSB-PD laminate method, and short-range force approach...
The folded sandwich structure might inevitably be impacted at low velocity when it is working, which will lead to the decline of mechanical properties. low-velocity impact resistance double-layer V-shaped aluminium researched by finite element method. It was found that damage mode and proportion energy absorption single-layer structures are different under impact, stiffness energy-absorbing capacity better than those small. In addition, in view response characteristics aluminum structure,...
Abstract This paper investigates a honeycomb sandwich structure that draws inspiration from the craft of origami. A specific folding pattern was applied to create origami‐based re‐entrant (ORH), aimed at improving energy absorption properties structure. The study on structures under low‐velocity impact (LVI) utilized both experimental and numerical approaches. were examined by conducting LVI tests with different then compared mechanical traditional (TRHSS). Additionally, refined finite...
