| Abstract Scope |
Thin layers and coatings are frequently used in a variety of applications, from biomedical to nuclear, to improve the in-use properties of components. However, due to the heterogeneities in their microstructure, they are susceptible to fracture under loading conditions. This topic is extensively investigated with advanced experimental approaches and supported by numerical models of different levels of complexity. Classical numerical solutions often neglect the complex crystalline or columnar morphology of such films and coatings, resulting in significant simplifications of the model that affect its predictive capabilities. To overcome this issue, a full-field model based on the digital material representation concept, which can explicitly take into account all local heterogeneities, is proposed within the work. Subsequent steps of model development, including generation of 2D/3D digital material representations, acquiring material properties at the appropriate length scale, incorporation of fracture models and finally examples of numerical predictions are presented within the work. |
