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,

Bauschinger effect in thin metallic films by fem simulations [PDF]

, 2013
Unpassivated free-standing gold and aluminum thin films (thickness ~ 200-400 nm, mean grain size dm,Au≈ 70-80nm, dm,Al≈ 120-200nm), subjected to tensile tests show Bauschinger effect (BE) during unloading [1, 2].

Numerical simulation of the mechanical response during strain path change: application to Zn alloys. [PDF]

The microstructure-based hardening model (Beyerlein and Tome, 2007), that accounts for the dislocation reversal-related mechanisms and the cut-through effect, is extended to HCP metals.

Cup Deep Drawing Simulation of Commercially Pure Titanium for Varying‐Shoulder‐Radius Die Using Finite Element Method and Non‐associated Flow Rule

steel research international, Volume 97, Issue 2, Page 827-837, February 2026.
Finite element simulations of deep drawing of commercially pure titanium sheets using single‐radius and varying‐shoulder‐radius dies are conducted. Two types of nonassociated flow rules are applied, and the results are verified by comparing them with the experimental results.

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.

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.

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.
