Time‐Dependent Settlement Model for Driven Piles Using Hybrid Finite Element‐Artificial Neural Network and Regression Approaches

Engineering Reports, Volume 8, Issue 9, September 2026.
This study investigates time‐dependent settlement of pile foundations. A hybrid framework combining Artificial Neural Networks and Finite Element Modeling was developed to derive an empirical equation for the pile‐soil system stiffness evolution over time. The model was validated and calibrated using laboratory test data.

Repeatability and Parasitic Out‐of‐Plane Motion in Controlled Rocking Structures With Cylindrical Columns: Results From Triaxial Shake Table Tests

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2930-2947, September 2026.
ABSTRACT Self‐centering rocking structures outperform conventional ones since they show zero post‐earthquake damage and excellent recentering; however, their applications remain limited due to concerns that rocking is extremely sensitive and nonrepeatable. This paper investigates the repeatability and parasitic out‐of‐plane motion of controlled rocking

Microscale FFT‐based modeling of artificial porous microstructures and analysis of macroscopic models under varying loading scenarios

GAMM-Mitteilungen, Volume 49, Issue 3, September 2026.
Abstract This article investigates the modeling of metallic isotropic porous materials by evaluating and comparing macroscopic and microstructure‐resolved simulation approaches. At the macroscopic level, different variants of the Deshpande‐Fleck (DF) model are implemented to describe the elastoplastic behavior of metallic porous materials.

Multiphysics model of swelling geomaterials based on Stern theory: Describing different swelling behaviors depending on exchangeable cation species

Journal of Rock Mechanics and Geotechnical Engineering
Limited models have been devised using Stern theory to obtain the repulsive force from a double layer. Moreover, an elastoplastic model that differentiates various swelling behaviors because of exchangeable cation species is yet to be devised.
