On certain fundamental issues in continuum damage mechanics

open access: yesJournal of the Mechanical Behavior of Materials, 2012
In this article, we discuss three fundamental issues in continuum damage mechanics. First, we investigate the nature of the damage process. For this purpose, we dissect the expression of the effective stress into an infinite geometric series and ...

The Foundations of Continuum Damage Mechanics

open access: yesProceedings 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.

Probabilistic fatigue life prediction of metallic components based on continuum damage mechanics

open access: yesXibei 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 ...

New tension-compression damage model for complex analysis of concrete structures [PDF]

open access: yes, 2016
A new damage model, based on continuum damage mechanics and simulating the opening, closing, and reopening of cracks in concrete using only one surface of discontinuity, is proposed in this article.

Numerical simulation of self-piercing riveting process (SRP) using continuum damage mechanics modelling [PDF]

open access: yesFracture 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 repairability index for reinforced concrete members based on fracture mechanics [PDF]

open access: yes, 2001
This paper proposes a repairability index for damage assessment in reinforced concrete structural members. The procedure discussed in this paper differs from the standard methods in two aspects: the structural and damage analyses are coupled and it is ...

Meso-scale modelling of 3D woven composite T-joints with weave variations [PDF]

open access: yes, 2019
A meso-scale modelling framework is proposed to simulate the 3D woven fibre architectures and the mechanical performance of the composite T-joints, subjected to quasi-static tensile pull-off loading. The proposed method starts with building the realistic

A Modified Fatigue Damage Model for High-Cycle Fatigue Life Prediction

open access: yesAdvances in Materials Science and Engineering, 2016
Based on the assumption of quasibrittle failure under high-cycle fatigue for the metal material, the damage constitutive equation and the modified damage evolution equation are obtained with continuum damage mechanics.
