A review of some plasticity and viscoplasticity constitutive theories
TL;DR: In this paper, the main ingredients and assumptions of developing macroscopic inelastic constitutive equations, mainly for metals and low strain cyclic conditions, have been discussed, with some comparisons with the previous ones, including more recent developments that offer potential new capabilities.

Continuum Models of Ductile Fracture: A Review
TL;DR: In this paper, the authors present a review of the material constitutive equations and computational tools which have been recently developed to simulate ductile rupture and fracture, which are used in structural computations.

Constitutive and damage evolution equations of elastic-brittle materials based on irreversible thermodynamics
Sumio Murakami,K. Kamiya +1 more
TL;DR: In this paper, the constitutive and evolution equations of elastic-brittle damage materials are developed on the basis of irreversible thermodynamic theory for constitutive equations, and a damage dissipation potential related to the entropy production rate is expressed in terms of damage conjugate force.
Continuum Models of Ductile Fracture: A Review
TL;DR: The approach based on Rice (1968) J-integral is widely used for industrial applications but suffers from various limitations: (i) it can only deal with pre-existing cracks and cannot be applied to model crack initiation and pro-pagation from a notch as discussed by the authors.

Fracture energy based bi-dissipative damage model for concrete
Claudia Comi,Umberto Perego +1 more
TL;DR: In this article, an isotropic damage model for concrete is presented, where the main features of the model are: limited number of constitutive parameters required; independent modelling of tension and compression behaviour by means of two damage variables and two separate activation criteria (bi-dissipative model); independent definition of tension/compression fracture energies; consistent modelling of the unilateral effect upon transition from tension to compression; and the effectiveness of fracture energy based regularization strategy.

Elastic moduli of a cracked solid
TL;DR: In this paper, a self-consistent method for the elastic moduli of bodies containing randomly distributed flat cracks, with or without fluid in their interiors, is proposed and general concepts are outlined for arbitrary cracks and explicit derivations together with numerical results are given.

Strain- and stress-based continuum damage models—I. Formulation
Juan C. Simo,J.W. Ju +1 more
TL;DR: In this article, a dual framework for elastic cap damage was proposed, where a strain-and a stress-based approach was employed, and a viscous regularization of strain-based, rate-independent damage models was also developed.

Continuum damage theory - application to concrete
TL;DR: This paper presents a review of the different models for concrete based on continuum damage theory, formulated at the Laboratoire de Mecanique et Technologie (Cachan, France), and the numerical implementations performed give a good description of the failure process as well as an accurate prediction of the behavior of concrete and reinforced concrete structures.
