Probabilistic fatigue life prediction of metallic components based on continuum damage mechanics
Xibei Gongye Daxue Xuebao, 2021 Based on continuum damage mechanics, a probabilistic method of predicting high-cycle fatigue life for metallic components is proposed. First, macro-meso two-scale stress-strain equations are established by combining Eshelby-Kroner localization law and ...

Numerical simulation of self-piercing riveting process (SRP) using continuum damage mechanics modelling [PDF]
Fracture and Structural Integrity, 2018 The extended Bonora damage model was used to investigate joinability of materials in self-piercing riveting process. This updated model formulation accounts for void nucleation and growth process and shear-controlled damage which is critical for shear ...

A Review on Fatigue Life Prediction Methods for Metals
Advances in Materials Science and Engineering, 2016 Metallic materials are extensively used in engineering structures and fatigue failure is one of the most common failure modes of metal structures. Fatigue phenomena occur when a material is subjected to fluctuating stresses and strains, which lead to ...

The Foundations of Continuum Damage Mechanics
Proceedings of International Structural Engineering and Construction, 2019 Damage Mechanics has become a useful theory in describing the nonlinear behavior of solids driven by the nucleation and growth of cracks and microcracks. This approach, based on the first principles of mechanics and thermodynamics, has also been combined with classical theories of plasticity to address a wide range of loading applications.

Rakenteiden Mekaniikka, 2019 A material containing spherical microvoids with a Hookean matrix response was shown to take the appearance usually applied in continuum damage mechanics. However, the commonly used variable damage D was replaced with the void volume fraction f , which has a clear physical meaning, and the elastic strain tensor \Bold {ε}^e with the damage-elastic strain

Fracture and permeability of concrete and rocks
Comptes Rendus. Physique, 2021 Continuum Damage Mechanics provides a framework for the description of the mechanical response of concrete and rocks which encompasses distributed micro-cracking, macro-crack initiation, and then its propagation. In order to achieve a consistent setting,
