Abstract
The significance of microstructural parameters for the damage and rupture of brittle materials is investigated by a numerical model that accounts for separation of grain interfaces. The microcracking approach refers to a specified material structure; synthetic random sampling allows for fluctuations. Thus, damage progression is simulated and the strength of material specimens is estimated by employing fracture mechanics within a microstructure that exhibits statistical variability. The issues addressed regard failure behaviour, strength level and sensitivity to microstructural parameters. Also discussed is the effect of specimen dimensions in connection with rupture.
