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.
