Numerical Homogenization of Single-Walled Corrugated Board with Imperfections
Applied Sciences, 2022 Numerical homogenization is an excellent tool for the quick simplification of complex structures with a model that is much simpler and, at the same time, accurately reflects the mechanical behavior of the original model.

An Abridged Review of Buckling Analysis of Compression Members in Construction
Buildings, 2021 The column buckling problem was first investigated by Leonhard Euler in 1757. Since then, numerous efforts have been made to enhance the buckling capacity of slender columns, because of their importance in structural, mechanical, aeronautical, biomedical,

Random fields of initial out of straightness leading to column buckling
Journal of Civil Engineering and Management, 2017 The elastic load-carrying capacity and buckling trajectory of steel columns under compression with open and hollow cross-sections, whose axis is curved by spatial random fields, are studied in the article. As a result of the spatial curvature of the axis

ON THE IMPERFECTIONS OF CRYSTALS [PDF]
Proceedings of the National Academy of Sciences, 1929 Imperfections of crystals may be either of mechanical or chemical nature. As will appear in the course of this investigation, the phenomena related to the chemical imperfections can hardly be understood without a preliminary knowledge of the mechanical defects of the crystals considered.

Analysis of load capacity of roof trusses with imperfections and the issue of equivalent load adoption [PDF]
Acta Scientiarum Polonorum. Architectura, 2021 The internal forces and stresses were analyzed and utilization of the design resistance in selected members of the roof structure with local and global geometrical imperfections was evaluated. Values of these imperfections were based on the information
