Continuum damage mechanics for the lithosphere [PDF]

open access: yesJournal of Geophysical Research, 2011
[1] This paper introduces a new mathematical formulation of continuum damage mechanics for deep lithospheric layers subjected to thermomechanical loading. The material's rheology includes isotropic linear elasticity as well as nonlinear viscoplasticity induced by combined creep mechanisms.

Springback Modeling in L-bending Process Using Continuum Damage Mechanics Concept

open access: yesJournal of Applied and Computational Mechanics, 2015
Springback is one of the most common and important issues in metal forming area. Due to it depends on variety of parameters, it is hard to predict. Hence, in this paper, the effect of continuum damage mechanics (CDM) based on the Lemaitre isotropic ...

A Stress Tensor-based Failure Criterion for Ordinary State-based ‎Peridynamic Models‎ [PDF]

open access: yesJournal of Applied and Computational Mechanics, 2022
Peridynamics is a recent nonlocal theory of continuum mechanics that is suitable to describe fracture problems in solid mechanics. In this paper, a new failure criterion based on the stress field is developed by adopting the damage correspondence model ...

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.

Modelling of brittle damage nucleation by means of ca [PDF]

open access: yesComputer Methods in Materials Science, 2007
The description of damage nucleation in metals subjected to creep conditions, on the level of material structure, is proposed. In classical approach of mechanics it is achieved by introducing scalar (or tensorial) parameter called damage variable and ...

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 ...
