elongation at breakEdit

Originally proposed at Wikidata:Property proposal/Natural science

Descriptionmaterial property; the ratio between changed length and initial length after breakage of the test specimen. It expresses the capability of a material to resist changes of shape without crack formation.
RepresentsElongation at break (Q991936)
Data typeQuantity
Template parameterThis proprety request is part of the project of creating an infobox for materials
DomainMechanical property of all solid Materials
Allowed valuesAny number. Since it depend on parameters such as thermic treatment, most materials will an have a upper and lower bound. Qualifiers : temperature (P2076) (shall be mandatory), pressure (P2077), determination method (P459), Moisture absorption (under creation).
Allowed unitspercent (Q11229)
Example 1SAE 316L stainless steel (Q28453931) → 55 percent (Q11229)
