20.500.12556/RUL-171900 Upogibna togost slojevitih plošč in ločnih struktur z origami sredico Bending stiffness of laminated plates and arch structures with origami core V nalogi je analiziran vpliv geometrije, perforacij in ukrivljenosti na upogibno togost slojevitih plošč z Miura origami sredico. Izdelani so bili ravni in ločni vzorci z različnimi geometrijskimi parametri, velikostmi perforacij in višinami loka. S tritočkovnimi poizkusi je bila ovrednotena togost glede na maso in površino. Rezultati so pokazali, da perforacije ne zmanjšajo nujno togosti. V nekaterih primerih so perforirani vzorci dosegli celo višjo nosilnost. Nižje ločne plošče so pri enaki masi izkazale večjo togost, kar omogoča učinkovitejšo zasnovo. The paper analyzes the influence of geometry, perforations, and curvature on the bending stiffness of layered plates with a Miura origami core. Flat and curved patterns with different geometric parameters, perforation sizes, and arc heights were fabricated. Three-point tests were used to evaluate stiffness in relation to mass and surface area. The results showed that perforations do not necessarily reduce stiffness. In some cases, perforated patterns achieved even higher load-bearing capacity. Lower curved plates exhibited greater stiffness for the same mass, enabling more efficient design.
