Architected Lattices with a Topological Transition
Advanced Engineering Materials, Volume 27, Issue 11, June 2025.This article develops topological metamaterials showing multidirectional two‐step deformation under compression by embedding contact‐enabled topological mechanisms into lattice structures. Experiments on 3D‐printed 2D and 3D lattices and finite element simulations are conducted to demonstrate the working principle of the topological metamaterials.

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.

Load-Carrying Capacity of Ultra-Thin Shells with and without CNTs Reinforcement
Mathematics, 2022 Isotropic ultra-thin shells or membranes, as well as cable–membrane structures, cannot resist loads at the initial state and always require a form-finding process to reach the steady state.

Symbolic manipulation in buckling and postbuckling analysis [PDF]
Computers & Structures, 1985 A perturbation procedure for the buckling and postbuckling analysis of elastic structures is shown to be well suited to be implemented as an automatic symbolic manipulation procedure. The postbuckling analysis of a circular arch is considered as an example, and the asymptotic description of the bifurcated equilibrium path is given. The main purposes of

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 ...

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 ...

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 ...
