PMD Core Ontology: Description back to ToC

The PMD Core Ontology (PMDco) is a comprehensive framework for representing knowledge that encompasses fundamental concepts from the domains of materials science and engineering (MSE). The PMDco has been designed as a mid-level ontology to establish a connection between specific MSE application ontologies and the domain neutral concepts found in established top-level ontologies. The primary goal of the PMDco is to promote interoperability between diverse domains. PMDco's class structure is both understandable and extensible, making it an efficient tool for organizing MSE knowledge. It serves as a semantic intermediate layer that unifies MSE knowledge representations, enabling data and metadata to be systematically integrated on key terms within the MSE domain. With PMDco, it is possible to seamlessly trace data generation. By building on this foundation, PMDco facilitates the integration of data from various sources and the creation of complex workflows. In summary, PMDco is a valuable tool for researchers and practitioners in the MSE domains. It provides a common language for representing and sharing knowledge, allowing for efficient collaboration and promoting interoperability between diverse domains. Its design allows for the systematic integration of data and metadata, enabling seamless traceability of data generation. Overall, PMDco is a crucial step towards a unified and comprehensive understanding of the MSE domain.

Behavioral Material Propertyc back to ToC or Class ToC

IRI: https://w3id.org/pmd/co/PMD_0000005

Technical materials are complex object aggregates. The properties that are determined for those object aggregates are intrinsically associated with the methodologies employed in the measurement process. This is in contrast to typical 'physical' properties, which like e.g. mass that can be determined to high accuracy independently of the measurement process. As a consequence, the behavoiral material properties in the ontology are differeciated according to their measurement method, e.g. Brinell hardness and Vickers hardness are different types of indentation hardness rather than different measures/quantification (GDC) of the materials property 'indentation hardness'. The 'unit idenifieres' of such properties (e.g. "HV1", "HV10", "HBW") are strictly speaking not units but rather references to the measurement methodology used to determine a numeric value that quantifies the property.

A property is a material trait in terms of the kind and magnitude of response to a specific imposed stimulus. Generally, definitions of properties are made independent of material shape and size. (Callister, W.D., Rethwisch, D.G., Materials Science and Engineering, Wiley, 2014) We only deal with intensive (system-size independent) materrial properties. Extensive properties that depend on the testpiece/specimen/probe size should be found in the respective testing method modules.

Coarse Grained Simulationc back to ToC or Class ToC

IRI: https://w3id.org/pmd/co/PMD_0000562

A Multiscale Simulation process that simplifies the system by grouping atoms or molecules into larger particles, thereby reducing computational complexity and allowing for the study of larger systems or longer time scales.

Example 
In materials science, coarse-grained simulations are often used to study the mechanical properties of polymers. For instance, in the simulation of polymer chains, each segment of the chain might represent a group of several monomers, rather than modeling every single atom. This approach allows researchers to investigate the behavior of polymeric materials over larger scales and longer time periods, such as the viscoelastic properties of a polymer melt.
