It is discussed how a two-step knowledge graph rewriting approach can be employed for aligning the domain ontologies with the European Materials and Modelling Ontology (EMMO), the top-level ontology used by VIMMP jointly with multiple related projects and platforms. This is illustrated by an example from molecular modelling and simulation.

A major concern is the long-term stability of adhesive joints, especially for metallic substrates exposed to corrosive media. The aim of this work is to investigate the delamination mechanisms occurring in a real closed adhesive joint geometry. To achieve this purpose, the potential distribution at the metal/polymer interface was measured by means of Scanning Kelvin Probe (SKP) through a thin layer of glass. Quantitative measurements of the delamination kinetics were performed, accompanied by XPS inspection of the fracture surfaces. The delamination rate was found to be hundred times slower than in an open joint geometry. Furthermore, the delamination-limiting step for the open joint is the transport of cations, whereas for the closed joint is limited by the ingress of...

One of the main advantages of the adhesives is the ability to bond dissimilar materials and the more efficient load transfer in comparison to other joining methods. Several industrial applications request the adhesive joint to withstand loads under different environmental conditions such as high moisture, and extreme temperatures. Thus, predicting the lifetime of adhesively bonded joints under moist environments is crucial to support tailoring the properties for the respective application demand. Relevant effects of water in adhesively bonded components may be strength degradation and introduction of stresses. Knowing the behaviour of the water in adhesive joints may contribute to directing the design of bonded components, lead to greater confidence and increase the use of adhesives in the industry. A significant cause of...
