Computational Fracture Mechanics

The research concentrates primarily on development of new methods for micromechanical fracture simulation of heterogeneous engineering materials with two dimensional discontinuous models. This includes impovement of random mesh generator base on Voronoi cells, procedures for appropriate modeling of heterogeneous material structure at meso and micro level, adaptation of dislocation theories for crack initiation and propagation simulations with dicontinuous models and development of new algorithms for progressive fracturing simulations. Another goal of the project is to further extend the possibilities of considering the material microstructure in classical fracture mechanics approaches with continuous finite element models, i.e. influences of grain boundaries, hard and soft inclusion, pores etc. on crack initiation and propagation. These models are applied to pitting problems on contacting surfaces of mechanical components, with the purpose of estimating the remaining service-life of a component with detected flaw or operating at the extreme range of its capacity.
