Fatigue Assessment of Precorroded AlSi9Cu3 Specimens Incorporating Short Crack Propagation

Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 5, Page 2054-2066, May 2025.
ABSTRACT This study investigates the fatigue behavior of AlSi9Cu3 aluminum die‐cast alloy after exposure to accelerated corrosive conditions. It underscores the significant impact of minor localized corrosion imperfections on fatigue strength and presents a numerically efficient method for fatigue assessment based on fracture mechanics principles ...

Vision‐based fatigue crack automatic perception and geometric updating of finite element model for welded joint in steel structures

Computer-Aided Civil and Infrastructure Engineering, Volume 39, Issue 11, Page 1659-1675, 1 June 2024.
Abstract Digital twin requires establishing a self‐updated model to simulate the structural damage perceived onsite. Despite the great success in damage identification and quantification, the difficulty in registration still limits the efficiency of model updating.

Potentials and limitations in finite element based crack propagation analysis using FRANC3D

, 2020
About 80% to 95% of all structural failures occur due to a fatigue mechanism1. Accurate fatigue assessment is therefore of great importance. This thesis focuses on a finite element analysis based approach, implemented in the program FRANC3D, to ...
