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.

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

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.

The optimization framework of identification for elastoplasticity
, 2010 本論文旨在研究彈塑性模式的識別問題,並且提出一致的方法來估測模式參數與初始狀態。本文特別注意實際收到的材料、既存的結構物，其內變數事實上不能假設初值為零。首先,提出一個廣泛的彈塑性模式。根據此模式,建立其彈塑性識別的動態最佳化架構。對於這個包含等式約束、不等式約束與互補約束的最佳化問題，本文獲得其正確的最佳化條件。文中所得結果之特色在於呈現凸與辛之特性。於現代實驗資料擷取朝向離散數位化之趨勢，本文除了處理識別之連續時間最佳化問題外,也考慮識別之離散時間最佳化問題,所得離散解條件也保有辛群之特性 ...
