Abstract
Microcracking due to thermal expansion anisotropy is considered based on a finite element model. A polycrystalline microstructure is generated via Monte Carlo simulation. Microcrack formation is investigated using a Griffith-type failure criterion. The effect of grain size on the threshold for microcrack initiation as well as on the accumulation of damage is analysed. The damage evolution can be described by a three-parametric Weibull distribution.Citation
