Complex Damage Variables in Continuum Damage Mechanics
Applied Mechanics and Materials, 2015The concept of complex damage variables is introduced in this work. These damage variables have both real and imaginary parts. They are introduced not to use them in practical applications but to try to derive a direct relationship between the damage due to cross-sectional area reduction and the damage due to elastic stiffness degradation.

On Representation of Damage Evolution in Continuum Damage Mechanics
International Journal of Damage Mechanics, 1997The effect of damage patterning on elastic moduli and damage evolution in ideal brittle cracked solids is examined. Key limitations associated with typical continuum damage mechanics approaches are addressed. Critical shortcomings arising from the use of spatially-averaged damage descriptors in the evaluation of effective moduli and thermodynamic ...

A NURBS-BEM Application in Continuum Damage Mechanics
Key Engineering Materials, 2018In this paper the integral equation approach is used to describe the propagation of continuumdamage in three dimensional solids. The governing equation is of integral type and contains bothboundary and domain integrals. Such integrals are computed with the aid of the NURBS functions.The subvolume involved by the damage is modelled by a special mapping ...

This chapter introduces the general concept of ductile damage, i.e. the development of microvoids and pores due to large plastic strains and deformations. The general definitions of damage based on a scalar damage variable as the surface damage variable or the void volume fraction are introduced and experimental approaches to measure the quantity of ...

Continuum Damage Mechanics (CDM) can be thought of as a subset of ISV theory as described earlier. It was introduced by Kachanov [1] and modified somewhat by Rabotnov [2]] has now reached a stage that practical engineering problems can be solved. In contrast to fracture mechanics which considers the process of initiation and growth of microcracks as a ...

Material Damage and Continuum Damage Mechanics
2011Continuum damage mechanics is a mechanical theory for analyzing damage and fracture processes in materials from a continuum mechanics point of view. The present chapter starts with the notion of material damage and that of continuum damage mechanics. Section 1.1 is concerned with the definition of damage, its mechanical aspects observed in different ...

Endochronic Theory of Continuum Damage Mechanics
Journal of Engineering Mechanics, 1998The constitutive framework presented accounts for the coupling between the damage process and the plastic deformation process. The model build its basis on the thermodynamic equivalence of an actual damaged continuum and an equivalent fictitious undamaged continuum.
