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.

Orientation-dependent yield and Bauschinger effects in two-dimensional Yukawa solids

Physical Review Research
Langevin dynamics simulations of two-dimensional (2D) Yukawa solids are performed to investigate the orientation-dependent yield and Bauschinger effects in solid 2D dusty plasmas.

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.

An Eulerian Framework for Modeling Visco‐Plasticity and Isotropic and Directional Material Hardening Utilizing Neural Networks

International 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 ...

Investigation of advanced strain-path dependent material models for sheet metal forming simulations [PDF]

, 2006
Sheet metal forming processes often involve complex loading sequences. To improve the prediction of some undesirable phenomena, such as springback, physical behavior models should be considered.

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

Fatigue &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.

The detrimental effect of autofrettage on externally cracked modern tank gun barrels

Defence Technology, 2019
Overstraining gun tubes has a twofold advantage. First, it enables the increase of the Safe Maximum Pressure (SMP) in the tube, resulting in a higher muzzle velocity which extends the gun's range and its projectile kinetic energy.

Bauschinger effect and coercivity in dual-phase steels

Chinese Physics Letters, 1984
Initial flow stresses and coercivities during and after tension and tension plus compression in ferrite-martensite dual phase steels have been measured. It was found that both parameters for tension plus compression are smaller than those for tension only. For the flow stress, this phenomenon is called Bauschinger effect.

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

Earthquake 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 ...
