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

Journal 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]

Physical 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 ...

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

Proceedings 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 ...

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

Materials 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,

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

Structural 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

Springback prediction of magnesium alloy sheet with nonlinear combined hardening

工程科学学报, 2017
Springback is regarded as one of the main defects that occur in sheet-metal forming processes. Therefore, improving its prediction accuracy, especially under highly nonlinear conditions, is important for researchers. In this paper, constitutive equations

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

Advanced 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 ...

A Full-Field Crystal Plasticity Study on the Bauschinger Effect Caused by Non-Shearable Particles and Voids in Aluminium Single Crystals

Metals
In the present work, the goal is to use two-scale simulations to be incorporated into the full-field open software DAMASK version 2.0.3 crystal plasticity framework, in relation to the Bauschinger effect caused by the composite effect of the presence of ...
