Impacts of the Superstructure on the Seismic Responses of Piled Raft Foundations: A 3D Nonlinear Dynamic Analysis Using Kinematic Hardening Constitutive Model

Engineering Reports, Volume 7, Issue 12, December 2025.
This study presents 3D nonlinear dynamic analyses of soil–pile–structure systems in clay through an advanced kinematic hardening constitutive model, along with experimental verifications. Findings highlight the impacts of the superstructure on the seismic responses of piled raft foundations.

Badanie Wpływu Efektu Bauschingera na Plastyczne Przystosowanie się do Konstrukcji (Na Przykładzie Układu Prętowego)

Engineering Transactions, 1974
The strain bardening hypothesis assumed exerts a certain influence on the shakedown of the structure. In the present paper the problem is reduced to an analysis of the influence of the Bauschinger effect on the shakedown process.

Athermal Nonlinear Elastic Constants of Amorphous Solids

, 2010
We derive expressions for the lowest nonlinear elastic constants of amorphous solids in athermal conditions (up to third order), in terms of the interaction potential between the constituent particles.

Seismic Capacity and Performance of Waffle‐Flat Plate Structures Under Near‐Fault Ground Motions: Bidirectional Shake Table Tests

Earthquake Engineering &Structural Dynamics, Volume 54, Issue 12, Page 3069-3089, 10 October 2025.
ABSTRACT A reinforced concrete waffle‐flat plate structure was subjected to a sequence of bidirectional near‐fault ground motions on a shake table until collapse. The test specimen was designed under current building codes and assigned a region of moderate seismicity.

An Eulerian Framework for Modeling Visco‐Plasticity and Isotropic and Directional Material Hardening Utilizing Neural Networks

International Journal for Numerical Methods in Engineering, Volume 126, Issue 17, 15 September 2025.
ABSTRACT A neural network is inserted into a theoretical framework for modeling the inelastic behavior of materials. The neural network replaces functional expressions for such phenomena as isotropic and directional hardening and viscoplasticity. The theoretical framework, into which the neural network is inserted, is Eulerian in the sense that all ...

Determination of Long-Range Internal Stresses in Cyclically Deformed Copper Single Crystals Using Convergent Beam Electron Diffraction

Crystals, 2020
Understanding long range internal stresses (LRIS) may be crucial for elucidating the basis of the Bauschinger effect, plastic deformation in fatigued metals, and plastic deformation in general.

A Plastic Damage Model With Mixed Isotropic–Kinematic Hardening for Low‐Cycle Fatigue in 7020 Aluminum

Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 6, Page 2649-2668, June 2025.
ABSTRACT The paper at hand presents a new numerical model based on experimental investigations of the low‐cycle fatigue behavior of the high‐strength aluminum alloy EN AW‐7020 T6. The developed plastic damage model is based on J2 plasticity with Charboche‐type mixed kinematic hardening blended with a suitable isotropic hardening.
