On certain fundamental issues in continuum damage mechanics
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
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]
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]
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
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
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.

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