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

Residual stress redistribution during elastic shake down in welded plates [PDF]
, 2018 Residual stresses are a consequence of welding in various structures such as ships and offshore structures. Residual stresses can be relaxed or redistributed according to the load levels during operation.

Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 7, Page 2949-2964, July 2025.Abstract Accurately predicting the fatigue lifetime of short fiber‐reinforced polymers (SFRPs) remains a significant challenge in the automotive industry, especially in the presence of sharp geometric discontinuities. This study presents a practical approach for estimating the fatigue life of injection‐molded notched SFRP specimens, considering ...

IMPLEMENTATION OF CONTINUUM DAMAGE IN ELASTO-VISCOPLASTIC CONSTITUTIVE EQUATIONS
TASK Quarterly, 2006 Modelling of the continuum damage framework is developed for application in the elasto-viscoplastic Chaboche constitutive model. A brief description of the basic variant of the Chaboche model equations is given, followed by a discussion of the most ...

Evolution of nonlocal damage in steel under cyclic straining [PDF]
, 2013 For high dynamic excitation, e.g. by earthquakes, the vibrations of steel structures lead to inelastic material behavior. Hystereses, developing under cyclic loading, are responsible for the dissipation of energy.

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.

Journal of Marine Science and Engineering, 2022 This work studies the Voce–Chaboche (V–C) material model parameter optimization for high-strength steel welded joints subjected to cyclic loading. The model parameters of each material zone in a S690 steel butt-welded joint were determined using an ...

Advanced Engineering Materials, Volume 27, Issue 8, April 2025.A novel metadata schema is introduced to address the sparsity of microstructure‐sensitive mechanical data. The design follows the material modeling workflow, as each run results in the definition of unique data objects. The schema includes categorical elements to ensure findability, accessibility, interoperability, and reusability (FAIR). This approach
