The Effect of Severe Plastic Deformation on Mechanical Properties for A6061 Aluminum Alloy Fabricated by Multitypes of Bending Forming

open access: yesMaterial Design &Processing Communication, Volume 2026, Issue 1, 2026.
Severe plastic deformation (SPD) is a well‐known processing technique used to impose large plastic strains and modify the mechanical properties of metal‐based materials. In this work, SPD was introduced into A6061 aluminum alloy sheets via two forming processes: differential diameter rolling (DDR) and V‐bending.

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

open access: yesEngineering 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.

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

open access: yesEarthquake 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

open access: yesInternational 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 ...

The Bauschinger Effect in Structural Aluminum Alloys

open access: yesEngineering Transactions, 1983
The paper presents test results for the Bauschinger effect on various structural aluminum alloys (PA7N, PA4N, PA2N). The experiments were carried out for the raw materiał, obtained directly from the factory. The rango of initial overstrain ew was 0.2 - 9%

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

open access: yesFatigue &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.

Bauschinger effect in uranium. [Rarefaction waves] [PDF]

open access: yes, 1976
The Bauschinger effect (different elastic-plastic behavior upon unloading) was measured in uranium and a model of the effect developed for use in one-dimensional hydrodynamic codes. Results from plate-impact tests show that rarefaction waves in uranium can be calculated more accurately with this model.
