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

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

Journal 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 ...

Advances 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 ...

Fatigue &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.

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

A Note on the Numerical Modelling of Viscoplastic Damage
Engineering 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.

JAPAN ARCHITECTURAL REVIEW, Volume 9, Issue 1, January–December 2026.ABSTRACT In this study, a material constitutive model based on the memory surface concept was proposed to reproduce the cyclic hardening and softening behaviors of SN490B structural steel under constant strain amplitude loading. The model incorporates combined isotropic and kinematic hardening rules, with strain‐amplitude‐dependent formulations ...
