Sažetak
The behavior of structures made of quasi-brittle materials, such as concrete, rock, ceramics or wood, is characterized by the localization of damage in a relatively narrow zone of the material. In the last two decades significant progress in the modeling of these materials has been achieved, however, due to the complexity of the problem, computational modeling of damage processes is still a challenging task. In the present paper a brief overview of the modeling possibilities in the framework of continuum mechanics is presented. The models are classified with respect to the kinematic assumption, constitutive framework and discretization technique. Each of these three items is briefly discussed. Subsequently, the microplane model for modeling of materials with strong initial anisotropy and the adaptive fixed crack model based on the multisurface plasticity are discussed in more detail. The application of the models is illustrated on two numerical examples. Finally, concluding remarks and future perspectives are presented.
