Development of a Finite Element Methodology for the Collapse Analysis of Composite Aerospace Structures [PDF]
, 2007 In this work, an analysis methodology for capturing the critical damage mechanisms leading to collapse in composite stiffened structures is proposed. One aspect of the methodology is a global-local analysis technique that monitors a strength criterion in

Proceedings in Applied Mathematics and Mechanics, Volume 25, Issue 4, December 2025.ABSTRACT The structural design optimization aims for robust structures with minimal use of material resources, leading to slender and thin‐walled structures, which entail a higher risk of stability problems. This issue is further influenced by geometrical imperfections, which are subjected to uncertainties.

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.
