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 ...

Modeling of Cyclic Plastic Behavior of SN490B Steel Using Hardening Rule With the Memory Surface Concept

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 ...

Tangent modulus in numerical integration of constitutive relations and its influence on convergence of N-R method [PDF]

Applied and Computational Mechanics, 2009
For the numerical solution of elasto-plastic problems with use of Newton-Raphson method in global equilibrium equation it is necessary to determine the tangent modulus in each integration point. To reach the parabolic convergence of Newton-Raphson method

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

Advances 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.

Mechanical Characterization and Damage Modeling of Adobe Blocks Stabilized With Natural Plant Fibers

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
This study evaluates the mechanical performance of adobe blocks stabilized with natural plant fibers derived from Hyparrhenia hirta (HH) and Stipa offneri (SO). To this end, adobe specimens were fabricated by incorporating plant fibers into the soil matrix at contents ranging from 0% to 1% by weight of soil, with increments of 0.2%.
