Memory of Stress History in Single and Two Surface Plasticity for Granular Soils

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 2, Page 597-612, 10 February 2026.
ABSTRACT Recent studies have identified limitations in Manzari and Dafalias' 1997 and 2004 sand plasticity models, particularly regarding one‐way unloading/reloading and ratcheting loading modes. These models are widely accepted as bounding surface models in the geotechnical engineering community; thus, concerns have arisen about a fundamental lack of ...

Experimental and Numerical Study of Mild Steel Behaviour under Cyclic Loading with Variable Strain Ranges

open access: yesAdvances in Materials Science and Engineering, 2016
To simulate the effect of variable strains on steel grades S275 and S355, an experimental displacement control test of plate specimens was performed. Specimens were tested under monotonic and cyclic loading according to the standard loading protocol of ...

A Note on the Numerical Modelling of Viscoplastic Damage

open access: yesEngineering Transactions, 2015
In this paper, a numerical model of the viscoplastic behaviour of metals including damage effects is proposed. The Chaboche model of constitutive equations accounting for viscoplasticity coupled to damage is applied.

Improvement of the Nonlinear Damage Mathematical Model for Steel Components in Bridge Under Complex Stress

open access: yesAdvances in Civil Engineering, Volume 2026, Issue 1, 2026.
To investigate the relationship between load, damage, and fatigue life of complex engineering components under stress, this paper modifies the existing continuous nonlinear damage model based on the distortion energy density theory to reflect the usage and stress characteristics of Q345 steel components in bridges.

Physics‐Informed Deep Learning Constitutive Model for Anisotropic and Pressure‐Dependent Behavior of Short Fiber‐Reinforced Polymers

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 126, Issue 19, 15 October 2025.
ABSTRACT Short fiber‐reinforced polymers (SFRPs) exhibit complex anisotropic, nonlinear, and pressure‐dependent behavior due to their heterogeneous microstructures. Conventional constitutive models, while accurate, require extensive parameter calibration and may lack generalization capability under varied loading conditions.

Modeling of Crack Propagation in Ductile Materials Under Cyclic, Proportional and Non‐Proportional Loading Conditions

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 10, Page 4505-4516, October 2025.
ABSTRACT The paper addresses the numerical calculation of multi‐axial fatigue crack propagation in ductile materials under proportional and non‐proportional cyclic loading conditions. The analysis is based on a phase field fracture theory proposed in earlier work, which describes crack propagation on the basis of the evolution of plastic strain.
