“…According to Liu et al (2023), there are many types of mobile dwellings, namely yurts, in turn, this leads to the need to implement several analyses and studies, which will gradually identify the national architectural totality with the mobile types of dwellings included in them, corresponding to the size of the production and economic activities of the ethnos. Tadina et al (2023) determined that mobile housing, the nomadic yurt is a unique result of the construction of a long development, step-by-step improvement of more conventional types of housing.…”

The use of the yurt dates to the 3rd millennium B.C. It was mentioned by the "Father of History" Herodotus, as well as by famous travellers Zemarh, Plano Carpini, Guillaume Rubruk, Ibn-Batuta and many others. The making of yurta and dombra was included in the representative list of non-material historical possessions of people. Today, there is a renewed interest in the construction of yurt dome structures suitable for the modern world. However, the techniques of doing them are not well known.In this context, this research examines the techniques of making dome structures for modern use by the structural mechanic method through the architectonics and design of central cyclic yurts.It explores the structural principles conceptualized and presents the ways to do so. It involves a two-story version of the yurt as a novel design. For instance, the yurt's second floor's primary structural components have been upgraded.The solution proposed allows to lower the dome of the yurt up to 0.8 m in winter. However, when it is cold and in case of expected strong steppe winds, the total diameter of the yurt remains the same. The number of uyks has also been reduced by the reduction of the length of two uyks out of three located next to each other, i.e., short side uyks are hinged to the main uyks located between kerege and shanyrak. This solution provides an economy of materials and creates space for the anchors during the movement of the shanyrak.

“…The common forms of sandwich structures include foams, 2 grids, 3 trusses, 4 and corrugations 5 . Notably, the compression, 6 bending, 7 vibration, 8 and impact resistance 9 performances have been investigated. Nowadays, honeycomb sandwiches are one of the most widely studied sandwich structures.…”

This article reports a carbon fiber–reinforced plastic Kagome composite honeycomb sandwich structure reinforced with polymethacrylimide (PMI) foam (PKCSS). Low‐velocity impact performances on the node, rib, and two cell centers of the PKCSS were experimentally compared with those on a composite Kagome honeycomb sandwich (CKHS), and the failure mechanism of the PKCSS was investigated. The impact process was analyzed through an explicit numerical analysis using ABAQUS. A three‐dimensional Hashin failure criterion was introduced using the VUMAT subroutine. Results confirmed that the PKCSS exhibits higher impact and specific loads than the CKHS, with the maximum improvements of 69.7% and 39.5%, respectively, under 50‐J impact energy. As an uncrushable material, the PMI foam provides strong impact resistance during its plateau stage. This technology of cell filling can be used to fabricate lightweight all‐composite honeycomb sandwiches for potential use in ultrahigh engineering applications.Highlights Cell filling is applied in an all‐composite Kagome honeycomb sandwich. The LVI performances of the PKCSS and CKHS are experimentally compared. C‐scanning is used to analyze the failure of the considered structures. The PKCSS's numerical model is established to investigate the impact process. The enhancement mechanism of the PMI foam is analyzed.

“…Furthermore, the absorbed energy values during perforation increased as the radius of curvature of the sandwich panels decreased. Liu et al 30 investigated the effect of radius of curvature on the drop hammer test results of sandwich composites with E‐glass/epoxy face sheets and PVC foam core. During LVI tests, contact forces increased while displacement values decreased as PVC core thickness and radius of curvature increased; however, the opposite was observed with specimens containing a thin PVC core.…”

The objective of this paper is to experimentally investigate how material and geometric parameters, including face sheet layup, curvature, and core finishing, affect the contact force‐displacement behavior, absorbed energy, and damage modes of curved sandwich composites with grid‐scored foam under low‐velocity impact loads. An instrumented drop‐weight testing machine with a hemispherical impactor was used to perform low‐velocity impact tests at different energy levels. Angled‐ply stacking had the maximum contact force and impact resistance for low curvature radii. In the event of penetration, the impact energy absorption of all curved sandwich panels increased as the curvature increased. The core finishing influenced the contact forces of the curved and flat sandwich panels but not the penetration energy. The curvature and face sheet layups affected the delamination size and pattern. Angle‐ply and cross‐ply face sheets with the smallest and maximum radius of curvature, respectively, decreased penetration depth. The resin‐filled channels reduced foam cell impact damage and face‐core debonding. LVI penetration resistance was found to be highest for angle‐ply stacking and knife‐cut foam at small curvature radii. The proposed research will also provide naval designers with valuable insight into the impact response of sandwich structures used in curved parts of the hull and deck.Highlights The effect of curvature on the LVI responses varied due to face sheet layups. Core finishing affected contact forces, but not the absorbed energy. Curvature and face sheet layups affected the damage modes. Resin‐filled channels limited damage area and acted as stoppers for debonding.
