An Investigation into the Different Hardening Models in Reverse Forming of Thin Sheets

open access: yesAdvances in Mechanical Engineering, 2009
This paper discusses a finite element analysis of the Bauschinger effect in the reverse cup drawing process, taken from the NUMISHEET′99 (Gelin and Picart, 1999) benchmark. In order to study the Bauschinger effect, several hardening models are considered

Finite Element Modelling of Rocking and Hybrid Precast Walls under Seismic Loading

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 9, Page 1924-1941, 25 July 2026.
ABSTRACT In recent years, self‐centring systems have received considerable research interest in the seismic design of precast concrete structures for their ability to limit damage and satisfy resilience requirements. Rocking and hybrid structural walls, characterised by the formation of a single gap at the wall–foundation interface, mitigate damage by ...

Strength–Ductility Balance in Additively Manufactured Laminated Fe‐Cr‐Ni/Fe‐Cr‐Ni‐Cu Alloy Heterostructures

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Fe‐Cr‐Ni‐Cu alloy has been extensively utilized over the past few decades due to its low cost yet high strength. Nevertheless, the poor ductility of this alloy limits its real application in industrial fields. In this study, a soft Fe‐Cr‐Ni alloy was combined with a Fe‐Cr‐Ni‐Cu alloy by laser‐directed energy deposition (LDED) to fabricate the ...

Back stress quantification in heterostructured metals: a comparative study of tension-compression and loading-unloading-reloading tests

open access: yesMaterials Research Letters
The Bauschinger effect, characterized by a reduction in yield stress upon load reversal, plays a critical role in both springback prediction and the understanding of back stress-mediated strengthening in emerging heterostructured materials. In this study,

Hybrid Data‐Driven and Physics‐Informed Learning of Cyclic Plasticity For Pipe Steel

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT An efficient and explainable machine learning (ML) approach is presented, replacing conventional material models based on the radial return mapping (RRM) algorithm for the constitutive modeling of cyclic plasticity in 3D. The application of transfer learning, based on an existing model for a separate class of steel, leads to a significant ...

Molecular dynamics simulation of reinforcement mechanism of graphene/aluminum composites and microstructure evolution

open access: yesJournal of Materials Research and Technology, 2023
Graphene/Aluminum (Gr/Al) composites with different graphene chirality and distribution patterns were established. The contribution of graphene interfaces to the mechanical properties of composites was investigated by using molecular dynamics methods ...

Plasticity-induced anisotropy in amorphous solids: The Bauschinger effect [PDF]

open access: yesPhysical Review E, 2010
Amorphous solids that underwent a strain in one direction such that they responded in a plastic manner `remember' that direction also when relaxed back to a state with zero mean stress. We address the question `what is the order parameter that is responsible for this memory?' and is therefore the reason for the different subsequent responses of the ...

Seismic performance evaluation of a century‐old RC columns for railway's structural concrete

open access: yesStructural Concrete, Volume 27, Issue 2, Page 2101-2125, April 2026.
Abstract Since the Great Kanto Earthquake of 1923 in Japan, reinforced concrete (RC) has been adopted for railway bridge piers, and some of these structures, now over 100 years old, continue to support transportation in the capital city of Tokyo. Evaluating the seismic performance of these few remaining RC structures has become an urgent issue. Because

Simulation‐Based Assessment of Second‐Order Residual Stress Fields on the Fatigue Performance of Silicon‐Strengthened Ferritic Ductile Irons

open access: yesAdvanced Engineering Materials, Volume 28, Issue 6, 18 March 2026.
This work presents a simulation‐based framework based on representative volume elements (RVEs) that explicitly incorporates process‐induced second‐order residual stresses into the fatigue strength assessment of ductile cast iron (DCI). For the first time, this approach enables a direct evaluation of the influence of second‐order residual stress fields ...
