PERFORMANCE COMPARISON OF LOCALIZATION LIMITERS
Květoň J., Eliáš J.
pages 375 - 378, full text

It is well known, that simulation of crack propagation using the finite element method is dependent on mesh discretization. The contribution compares two approaches that are designed to reduce the mesh influence: (I) the crack band model and (II) the nonlocal model. These localization limiters are applied to simulate three-point-bent beam with and without notch. The model of the beam is made with several variants of mesh discretization differing in finite element size and inclination. Performance of both localization limiters is discussed.
