Anisotropy in continuum damage mechanics
Scripta Metallurgica et Materialia, 1993The theory of continuum damage mechanics, first proposed by Kachanov, deals with the effects of damage due to the presence and coalescence of microcracks on the mechanical properties of materials. Different models of continuum damage mechanics have been proposed during the last two decades.

Decomposition of Damage Tensor in Continuum Damage Mechanics
Journal of Engineering Mechanics, 2001The principles of continuum damage mechanics are reviewed first for the case of uniaxial tension. The damage variable is then decomposed into two variables called crack damage variables and void damage variables. A consistent mathematical formulation is presented to decompose the damage tensor into two parts: one caused by voids and the other caused by

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 ...
