A total of 21 beams were tested under three-point bending to evaluate their load capacity, failure mechanisms, strain evolution, and cost performance. The specimens included 15 hybrid beams with various shear connection methods—resin-bonding, resin-bonding plus I-shaped GFRP profiles, and resin-bonding plus steel bolts at different spacings—as well as six control beams without SIP formworks for comparison. The complex microscale failure mechanisms were visualized through μXCT scanning. Results indicated that GFRP connectors demonstrated the highest bonding performance and load capacity among all connection methods, while steel bolt connectors provided the best post-failure ductility. The incorporation of SIP formworks significantly enhanced the structural performance of the hybrid beams, maximizing the utilization of UHPFRC’s high compressive strength. Compared to traditional reinforced UHPFRC beams, the hybrid beams achieved 22.7% higher peak loads while reducing UHPFRC usage by 63.2%.

The numerical model, incorporating the three-dimensional Hashin failure criterion via the VUMAT subroutine, was established to predict the bending failure process and damage energy of UV-CGFR composites from the perspectives of fracture damage and energy dissipation. The effects of curing time, UV irradiation intensity, and loading rate on the bending properties and bending failure mechanism of UV-CGFR composites were systematically investigated. The primary failure modes observed were resin compression-tensile fractures, fiber tensile fractures, interlaminar debonding, and delamination. The bending strength and bending modulus of UV-CGFR composites increase and decrease with the increase of curing time and irradiation intensity; the bending strength increases with the loading rate, and the bending modulus is less affected by the loading rate. The temperature rise effect generated by fiber tensile fractures and interlaminar debonding was identified as a key factor contributing to the enhancement of bending strength. The temperature increase became more pronounced with higher loading rates, reaching a maximum rise of 5.2℃. Furthermore, the feasibility of UV-CGFR composites for pipeline repair was validated through pipe ring bending tests.

In order to further enhance the energy absorption capacity of multi-cell bi-tubular tubes, this paper proposes an asymmetric gradient hierarchical bi-hexagonal tube (AGBT), which draws inspiration from the microstructure of the impact region of shrimp chelipeds and asymmetrical tree-like fractal structures. The results show that, under equal wall thickness conditions, the specific energy absorption and crushing force efficiency of the proposed 3rd order asymmetric gradient hierarchical bi-hexagonal tube (AGBT-3) are respectively 1.82 and 1.47 times higher than those of the conventional bi-hexagonal tube.

These findings establish a clear advantage of the proposed AGBT-3 over AGBT-0 in terms of crashworthiness. Additionally, this study also conducts a theoretical prediction of the mean crushing force of the proposed AGBT, based on the simplified super folding element theory, and observes a good agreement between the theoretical prediction and numerical results.

Airplanes equipped with honeycomb core sandwich panels are susceptible to hail impact damage. This type of damage can cause barely visible impact damage (BVID), which affects the core but not the face sheets. The main objective of this study is to examine the failure mechanisms of the Nomex honeycomb sandwich panel when subjected to single, repeated (i.e. at the same location), and multiple (i.e. at different locations) hail impacts. The experimental study was conducted to investigate the hail’s behavior upon impact on rigid structures and, subsequently, to assess the failure modes of sandwich structures under repeated hail impacts. The objective was to develop a suitable numerical model for studying the response of sandwich structures under multiple and random hail impacts. The sandwich panel, which consisted of four layers of woven glass epoxy as the face sheet and a Nomex honeycomb layer with a thickness of 16 mm as a core, was tested for its resilience to repeated hail impacts with 5, 10, 15, and 20 impacts. Four failure mechanisms were observed in the sandwich plate, including delamination growth at the top face sheet and three types of failure in the core. The core failures, initiated with wrinkling of the core walls, progressed to wall rupturing at higher impacts and, after 15 impacts, separated the face sheet from the core. Numerical models were then deployed to investigate the effects of hail size in a single impact and the effect of the random distribution of multiple hail impacts. The severity of damage caused by multiple impacts from lower-energy hail (30 mm in size at 21 m/s) was in a similar level as damage from a single impact by higher-energy hail (&gt;40 mm in size at 30 m/s).
