Odhad hodnoty lomové energie a velikosti lomové procesní zóny v tělesech z cementových kompozitů - numerický experiment
Original language description
Presented paper is focused on fracture process zone (FPZ) of quasi-brittle materials and energy dissipated within thiszone (local fracture energy) during fracture process. Fracture energy is used here from the point of view of two non-linear approaches to modelling of quasi-brittle fracture - cohesive crack models and equivalent elastic crack models. The paper deals with the influence of specimen size and relative notch length on the value of local fracture energy and size of FPZ. The rtesearch is conducted by means of numerical simulations of three-point bending tests of notched beams witch three specimen sizes. The simulations of fracture tests are performed by using ATENA finite element method software.
