Abstract Intelligent impact‐protection wearable devices often require intricate circuitry to operate, which hinders the timely display of impact‐related injuries. Consequently, it is imperative develop intelligent protective materials that are self‐sufficient and capable visualization. In this work, impact protection material shear‐stiffening gel (SSG) combined with mechanoluminescent (ML) ZnS:Cu/PDMS@SiO 2 create ML‐SSG. This embodies various features, including protection, force visualization, flame resistance, long‐distance passive control, making ideal for devices. light significant shear stiffening effect SSG, ML‐SSG effectively dissipates up 80% energy exhibits excellent resistance. Concurrently, also visualizing injuries, displaying warning in real‐time via mechanoluminescence, assessing based on intensity mechanoluminescence. The incorporation SiO ZnS:Cu has resulted remarkable flame‐retardant property. innovative significantly improves performance complex environments. addition, realizes human–computer interaction through neural network mechanoluminescence characteristics. research expands potential applications multifunctional complicated environments, thereby promoting development

Mechanical Properties Analysis of the New Bionic Honeycomb Structure Under Out-of-Plane Crushing

Опубликована: Янв. 1, 2025

Honeycomb is a kind of material with excellent performance, such as being lightweight and high-strength, widely used in aerospace, automotive, construction, other fields. Inspired by the natural turtle shell, novel bionic honeycomb structure devised adding inner tubes sinusoidal ribs to traditional hexagonal honeycomb. The crashworthiness this innovative was meticulously assessed using numerical simulations theoretical analysis methods. results revealed that new surpasses under same thickness. It noted performance more fully utilized when amplitude rib closer quarter period (T/4). Additionally, an increase structure's thickness correspondingly elevates its crashworthiness. In summary, based on simplified super folding element theory, we introduced predictive model for crushing force structure. prediction shows consistency results.
