Abstract: A microplane model, in which the constitutive properties are characterized independently on planes of various orientations (microplanes), is presented. It is found that the basic scheme previously developed for concrete ...

Abstract: AS a simpler alternative to a previous microplane model, a new microplane model is presented, in which the relative slipping of clay platelets is characterized by normal rather than shear strains on the microplanes. As is ...

Abstract: A generalized microplane model for brittle‐plastic heterogeneous materials such as concrete, which describes not only tensile cracking but also nonlinear triaxial response in compression and shear, is presented. The ...

Abstract: The general microplane model formulated in Part I of this study is calibrated and verified by comparison with numerous nonlinear triaxial test data from the literature and good agreement is achieved. The model involves ...

Abstract: A simple but general model for normal/shear cracking in quasi-brittle materials is presented. It is defined in terms of the normal and shear stresses on the average plane of the crack and the corresponding normal and shear ...

Abstract: The paper presents an improvement of the microplane model for concrete—a constitutive model in which the nonlinear triaxial behavior is characterized by relations between the stress and strain components on a microplane ...

Abstract: An appealing approach to formulate constitutive models for characterizing distributed damage due to microcracks and voids is continuum damage mechanics with the concepts of effective stress and strain equivalence. In that ...

Abstract: The new microplane model developed in the preceding companion paper is calibrated and verified by comparison with test data. A new approximate method is proposed for data delocalization, i.e., decontamination of laboratory ...
