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 ...

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 ...

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

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 ...

Fatigue Damage Estimation through Continuum Damage Mechanics

open access: yesProcedia Engineering, 2017
Abstract The paper presents an experimental investigation of the fatigue damage behavior of AISI 1020 steel using plasticity coupled continuum damage mechanics (CDM) model. The Model is based on the thermodynamics, a continuum damage variable, D and on the effective stress concept.

Towards stochastic continuum damage mechanics

open access: yesInternational Journal of Solids and Structures, 2020
Abstract In classical continuum damage mechanics, the distribution of cracks over differently oriented planes is an even deterministic function defined on the unit sphere. The coefficients of its Fourier expansion are completely symmetric and completely traceless tensors of even rank, the so-called fabric or damage tensors.
