A continuum damage model for composite laminates: Part II – Computational implementation and validation
TL;DR: In this article, the authors describe the computational implementation of a new damage model for laminated composites proposed in a previous paper, which is assured by regularizing the energy dissipated at a material point by each failure mechanism.

Prediction of size effects in notched laminates using continuum damage mechanics
TL;DR: In this paper, the authors examined the use of a continuum damage model to predict strength and size effects in notched carbon-epoxy laminates and found that the model is the most accurate technique to predict size effects.

Accurate simulation of delamination growth under mixed-mode loading using cohesive elements: Definition of interlaminar strengths and elastic stiffness
TL;DR: In this paper, a methodology for predicting accurately the propagation of delamination under mixed-mode fracture with cohesive elements is proposed, where relations between the interlaminar strengths and the penalty stiffness are proposed which ensure a correct energy dissipation when delamination propagates.

Crack band theory for fracture of concrete
Zdeněk P. Bažant,Byung H. Oh +1 more
TL;DR: In this article, a fracture theory for a heterogenous aggregate material which exhibits a gradual strain-softening due to microcracking and contains aggregate pieces that are not necessarily small compared to structural dimensions is developed.

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.
