Stress-driven solution to rate-independent elasto-plasticity with damage at small strains and its computer implementation
TL;DR: In this article, a fractional-step time discretisation is devised with the purpose to obtain a numerically efficient scheme converging possibly to a physically relevant stress-driven solutions, which however is to be verified a-posteriori by using a suitable integrated variant of the maximum-dissipation principle.
An interface element for the numerical analysis of fibre reinforced concrete
TL;DR: In this paper, a constitutive model for a joint element is developed based on a generalisation of the Cohesive Crack Model, which uses a dual external (tractions and crack opening vector), and internal variables, the latter of damage nature, responsible for the evolution of the softening cohesive.

Discussion of Two Crystal Plasticity Models Coupling with Anisotropic Damage for Finite Deformations
M. H. Liu,L. Feng +1 more
TL;DR: In this paper, two large deformation crystal plasticity models taking into account of anisotropic damage effect are presented and discussed, and the constitutive models are formulated by using the theory of continuum damage mechanics and the internal state variable theory.

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.
