Delamination Prediction by Continuum Damage Mechanics [PDF]

open access: yes, 1999
The present study describes the basic principles of a general damage approach for laminates and demonstrates its prediction possibilities for simulating the complete fracture phenomenon in the case of the initiation and propagation of delamination. In this paper, the Damage Mechanics Approach is presented to solve delamination problems such as the ...

Basic concepts and models in continuum damage mechanics [PDF]

open access: yes, 2007
In this paper, we present some basic elements of macroscopic modelling of damage. We then recall the general approach of continuum damage based on the thermodynamics of irreversible processes and its application to isotropic damage modelling.

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 ...

Simulating ice-shelf extent using damage mechanics

open access: yesJournal of Glaciology, 2022
Inaccurate representations of iceberg calving from ice shelves are a large source of uncertainty in mass-loss projections from the Antarctic ice sheet. Here, we address this limitation by implementing and testing a continuum damage-mechanics model in a ...

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 ...

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.

Analyzing the characteristics of the cavity nucleation, growth and coalescence mechanism of 9Cr-1Mo-VNb steel (P91) steel [PDF]

open access: yes, 2013
Creep damage is one of the serious problems for the high temperature industries and computational approach (such as continuum damage mechanics) has been developed and used, complementary to the experimental approach, to assist safe operation.
