Parameter-refreshed Chaboche model for mild steel cyclic plasticity behaviour

open access: yesPeriodica Polytechnica Civil Engineering, 2013
The development of a steel material model in order to follow the cyclic plastic behaviour is essential in seismic design. The authors present an improved Chaboche model for the cyclic mechanical behaviour of structural steel. The model is based on the combination of nonlinear kinematic and multi-linear isotropic hardening with a parameter refreshing ...

Crystal Plasticity Finite Element Modeling on High Temperature Low Cycle Fatigue of Ti2AlNb Alloy

open access: yesApplied Sciences, 2023
Ti2AlNb alloy is a three-phase alloy, which consists of O phase, β phase and α2 phase. Because of the difference in the mechanical characteristics between phases, Ti2AlNb alloy often exhibits deformation heterogeneity. Based on EBSD images of the Ti2AlNb

Physics‐Guided Transfer Learning for Predicting Stress–Strain Curves With Limited Experimental Data

open access: yescScience, Volume 2, Issue 1, March 2026.
ABSTRACT Many measurements in materials science are expressed as full response curves rather than single scalar values. Nevertheless, predicting entire curves reliably from limited experimental data remains challenging. Here, we address this problem for hot‐deformation stress–strain curves using a physics‐guided transfer learning (PGTL) framework that ...

Dynamic Models of Magma Storage Within a Damaging, Strain‐Softening Crust and Their Application to Sierra‐Negra's Pre‐Eruptive Inflation Pattern

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Prior to its 2005 and 2018 eruptions Sierra Negra's caldera displayed decades‐long inflation characterized by successive transient uplifts culminating in accelerating uplifts in the 1–2 years prior to each eruption. These observations motivated the question: can these transient uplifts be explained by internal dynamics of the magma system ...

Simulation of Large-Strain Tensile Necking in Single-Crystal Copper Specimens

open access: yesMetals
The mechanical behavior, the necking process and the geometry of the neck in rectangular cross-section single-crystal copper specimens under macroscopic uniaxial large-strain tensile conditions were numerically simulated and analyzed using the classical ...

Methodology for Multiaxial Fatigue Assessment of 2024‐T351 Aluminum Alloy Under Load Paths Representative of Aeronautical Structures

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 3, Page 979-997, March 2026.
ABSTRACT Bolted assemblies are widely used in aerospace, automotive, and railway industries, where they experience complex multiaxial loadings. Understanding the multiaxial fatigue behavior of materials in such joints is essential for ensuring structural durability.
