Abstract
The project is intended to develop new computational models for micromechanical simulation of progressive fracturing in heterogeneous engineering materials. Micromechanical models within the concept of the finite element analysis provide for simulation of material behaviour on micro-material level and can take into consideration the influence of material heterogeneity on failure processes of modern structures. Micro-material level can be reproduced with dense spatial network of connected beam, truss or cell elements, which can together with appropriate mathematical functions reproduce micro-mechanical behaviour such as dislocation motion along persistent slip bands or cleavage within crystal grains. Only a small number of single valued parameters are needed, which can be tuned in a relatively simple manner to experimental data. Preliminary research shows that the fracturing processes observed in real materials can be simulated to a higher degree of accuracy by using these models. The suitability of newly developed models for the fracture simulation of various engineering materials will be investigated.
