Vibration-assisted fabrication of thin shells with spatially distributed imperfections [PDF]
Nature CommunicationsThin-shell structures, found in biological systems such as beetle carapaces and widely used in aerospace and civil engineering, achieve remarkable strength-to-mass ratios given their slenderness and curved geometries. However, their load-bearing capacity

INFLUENCE OF GEOMETRICAL AND STRUCTURAL IMERFECTIONS OF STEEL PLATE GIRDERS
Facta Universitatis. Series: Architecture and Civil Engineering, 2021 The girders or parts of the girders are not ideally flat in terms of their geometry. The deviations that occur are defined as geometric imperfections.

Use of interpolation methods for modeling the stress-strain state of operated oil storage tanks
Structural Mechanics of Engineering Constructions and Buildings, 2023 The aim of the research is the comparison of two approaches for computer modeling of the stress-strain state of thin-walled shells of engineering structures, considering the imperfections of the geometric shapes arising due to their operation. The object

Effect of geometric imperfections on the ultimate moment capacity of cold-formed sigma-shape se
HBRC Journal, 2017 In recent years, cold formed steel sections are used more and more as primary framing components and as a secondary structural system. They are used as purlins and side rails or floor joist, and after that in the building envelops.
