International Journal for Numerical Methods in Engineering, Volume 126, Issue 1, 15 January 2025.ABSTRACT The structural properties of mechanical metamaterials are typically studied with two‐scale methods based on computational homogenization. Because such materials have a complex microstructure, enriched schemes such as second‐order computational homogenization are required to fully capture their nonlinear behavior, which arises from nonlocal ...

AI‐Driven Strength Prediction for Concrete‐Filled Steel Tube Column
Applied Computational Intelligence and Soft Computing, Volume 2025, Issue 1, 2025.This article explores a simplified method to predict the load‐carrying capacity of concrete‐filled steel tubular (CFST) columns and analyzes 13 different types of CFST composite columns. The analysis emphasizes the significance of having sufficient high‐quality experimental data to improve the accuracy of prediction models.

Advances in Materials Science and Engineering, Volume 2025, Issue 1, 2025.This study presents a comprehensive analysis of the impact of cracks on the buckling behavior and load capacity of column structures using the finite element method (FEM). The primary objective is to investigate how crack locations and orientations affect the critical load capacity and deformation patterns of columns and to develop and validate ...

Post-buckling behaviour of slender structures with a bi-linear bending moment-curvature relationship [PDF]
, 2007 Certain classes of slender structures of complex cross-section or fabricated from specialised materials can exhibit a bi-linear bending moment–curvature relationship that has a strong influence on their global structural behaviour.

Advances in Materials Science and Engineering, Volume 2025, Issue 1, 2025.Reinforced concrete columns (RCCs) are critical load‐bearing elements in structural systems, where stability is often governed by buckling, particularly in slender members subjected to axial compression. While extensive studies exist on column buckling, there remains a need for integrated approaches that couple analytical formulations with advanced ...

Topology optimization for stiffened panels, from linear buckling to postbuckling
, 2023 This study introduces topology optimization for postbuckling of stiffened panels. A level-set-based topology optimization parameterization, which has been successfully applied to linear buckling optimization, is extended to postbuckling optimization of ...

International Journal for Numerical Methods in Engineering, Volume 125, Issue 24, 30 December 2024.Abstract Mixed Finite Elements (FEs) with assumed stresses and displacements provide many advantages in analysing shell structures. They ensure good results for coarse meshes and provide an accurate representation of the stress field. The shell FEs within the family designated by the acronym Mixed Isostatic Self‐equilibrated Stresses (MISS) have ...
