Dislocations are particularly important defects in MSE as they are responsible for plastic deformation in metals. Controlling the evolution of dislocations allows tailoring material behaviors on multiple length scales. This PP is based on the ERC Starting Grant project “MuDiLingo – A Multiscale Dislocation Language for Data-Driven Materials Science”. Here, formal ontologies shall be designed together with TA-OMS: Dislocations are/can be treated as one-dimensional mathematical lines; they exist as defects in a crystal structure. “Local rules” are responsible for a specific type of topology change of such dislocation networks. Together with boundary conditions and additional governing equations that define physical relationships this use-case develops an idealized conceptualization for which a formal ontology as an explicit specification will be created. The ontology shall be extended towards idealized representations of other defects such as, e.g., grain boundaries or point defects.
