Add relevant process classes (mainly Process subclasses) that are necessary to describe cable bundle user case based on the review of previous first version of mechanical-testing ontology.

Currently, the NotchedSpecimen class is defined as equivalent to the following class expression,

MechanicalTestingSpecimen
 and (hasProperty some 
    (StressConcentrationFactor
     and (hasQuantityValue exactly 1 (Real
     and (hasNumericalData some xsd:double[> "1.0"^^xsd:double])))))
 and (hasSpatialDirectPart some SpecimenNotch)

or, in a simplified way, MechianicalTestingSpecimen and X and (hasSpatialDirectPart some SpecimenNotch).

According to some domain experts, we should replace this definition by two separate class expressions,

MechanicalTestingSpecimen
 and (hasProperty some 
    (StressConcentrationFactor
     and (hasQuantityValue exactly 1 (Real
     and (hasNumericalData some xsd:double[> "1.0"^^xsd:double])))))

and,

MechanicalTestingSpecimen and (hasSpatialDirectPart some SpecimenNotch)

because from a StressConcentrationFactor greater than 1 it directly follows that the specimen is notched, even if this was not specified directly through some hasSpatialDirectPart SpecimenNotch.

This is clearly wrong, as such constraint allows series to contain only one specimen. Should be replaced by a constraint meaning at least one specimen.

Describe duther the steel nomenclature by adding the following classes:

• SteelNomenclature
• AlloyedSteels and subclasses

UniversalTestingMachine is NOT equivalent to a Tensile Testing Machine .

The mechanical testing specimen shape (flat or round) is specified based on the geometry of the cross section (rectangle, circle).

A previous version (in alpha stage) was moved from gitlab (in branch https://github.com/emmo-repo/domain-mechanical-testing/tree/initial_move). This version needs the following before merging with master.

1. cleanup
2. updating EMMO
3. adding missing terms and relations
4. completing the Oyster EMMO
5. updating acknowledgement to developers and projects.

add annotations (comment, elucidation) to classes and properties of the Mechanical Testing Domain ontology

Add Taping concept in the Cable Bundle user case ontology - taping is defined as a type of Cable bundle cover.

Add relevant process classes (mainly Process subclasses) that are necessary to describe fatigue user case based on the review of previous first version of mechanical-testing ontology.

I was wondering how can be visualize the ontology. I did try with http://vowl.visualdataweb.org and with EMMO-python but in both cases appear some errors.
Could be share some instructions to load the ontology?

Most properties make sense at both the series level and the specimen level, but if the user creates instances of the data which only have the data attached to either the series or the specimen, there is no logic in place to make the other ontology individual inherit these properties, making some reasoning tasks infeasible with such data.

Examples of such properties are the StressConcentrationFactor, the MaterialNumber or the LoadingType.
