Originální abstrakt

The paper shows some results of a computational modelling focused on the occurrence of damage in heterogeneous materials, mainly with brittle matrix, especially on the issue of modelling crack formation and propagation. The attention is paid to the application of the finite element method to the buildings materials in order to find critical parameters determining behaviour of materials at damage process with reference to the history of several approaches to solving this problem. The applications of damage mechanics and possible approaches to model the origin of a crack propagation through modifications in FEM systems are presented and some practical applications are tested. Main effort is devoted to cement fibre composites and the search for new methods for their more accurate modelling, especially ahead of the crack tip. Modified XFEM method and its suggested modifications as to proper modelling of the real stress distribution close to crack tip are shown.
