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 ...

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

open access: yesEngineering 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.

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.

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

open access: yesCrystals, 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.

Surface construction for orthrotropic perfectly elastic-plastic Murnaghan material

open access: yesВесці Нацыянальнай акадэміі навук Беларусі: Серыя фізіка-тэхнічных навук, 2021
The problem of constructing a yield surface is described. The magnitude of the stress velocity potential is explained graphically. The parameters of an elastic-plastic process are introduced: a modified R.

Challenges and Lessons Learned From Pseudo‐Dynamic Hybrid Simulations on Ductile Steel Braced Frame Systems

open access: yesEarthquake Engineering &Structural Dynamics, Volume 54, Issue 4, Page 1229-1250, 10 April 2025.
ABSTRACT Performance‐based seismic design, which emerged more than two decades ago, requires accurate numerical models to capture the response of structural elements that undergo inelastic deformations under random loading histories. High‐fidelity benchmark test results under real natural hazards are therefore required to assist researchers and ...

Seismic loss comparison for buildings designed with ductile steel seismic force‐resisting systems and with controlled rocking braced frames

open access: yesEarthquake Spectra, Volume 41, Issue 1, Page 608-635, February 2025.
Observations from past earthquakes have highlighted the structural damage and significant residual deformations experienced by ductile steel seismic force‐resisting systems (SFRSs), such as special moment resisting frames (SMRFs), special concentrically braced frames (SCBFs), and buckling‐restrained braced frames (BRBFs).

Effective elasto‐(visco)plastic coefficients of a bi‐phasic composite material with scale‐dependent size effects

open access: yesMathematical Methods in the Applied Sciences, Volume 48, Issue 1, Page 926-979, 15 January 2025.
We employ the theory of asymptotic homogenization (AH) to study the elasto‐plastic behavior of a composite medium comprising two solid phases, separated by a sharp interface and characterized by mechanical properties, such as elastic coefficients and “initial yield stresses” (i.e., a threshold stress above which remodeling is triggered), that may ...
