Originally proposed at Wikidata:Property proposal/Natural science

   Done: toughness (P5520) (Talk and documentation)
DescriptionMaterial proprety measuring the ability of a material to absorb energy and plastically deform without fracturing.
Representsbase material (Q214609) > mechanical property of materials (Q5725005) > toughness (Q486802)
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 absorbtion.
Allowed unitsKJ/m3, J/m3, KJ/m2, J/m2, J/m, J/cm, J, ft-lb, ft-lb/in...
Example 1SAE 316L stainless steel (Q28453931) → 325 J / 76 ft-lb determination method (P459) → Charpy V-notch, temperature (P2076) → 30ºC pressure (P2077) → 1 bar [1]
Example 2nylon 6-6 (Q7071155) → 0.267 to 7.47 J/cm / 0.500 - 14.0 ft-lb/in determination method (P459) → Izod Impact, Notched, temperature (P2076) → 23ºC pressure (P2077) → 1 bar [2]
Example 3nylon 6-6 (Q7071155) → 0.0612 - 5340 J/cm / 0.115 - 10000 ft-lb/in determination method (P459) → Izod Impact, Unnotched, temperature (P2076) → 23ºC pressure (P2077) → 1 bar [3]
Example 4nylon 6-6 (Q7071155) → 3.00 kJ/m² / 1.43 ft-lb/in² determination method (P459) → Izod Impact, Notched (ISO), temperature (P2076) → 23ºC pressure (P2077) → 1 bar [4]
Example 5nylon 6-6 (Q7071155) → 60.0 kJ/m² / 28.6 ft-lb/in² determination method (P459) → Izod Impact, Unnotched (ISO), temperature (P2076) → 23ºC pressure (P2077) → 1 bar [5]
Example 6nylon 6-6 (Q7071155) → 4.50 J/cm² / 21.4 ft-lb/in² determination method (P459) → Charpy Impact Unnotched, temperature (P2076) → 23ºC pressure (P2077) → 1 bar [6]
Example 7nylon 6-6 (Q7071155) → 0.300 J/cm² / 1.43 ft-lb/in² determination method (P459) → Charpy Impact, Notched, temperature (P2076) → 23ºC pressure (P2077) → 1 bar [7]

Planned useCreating an infobox for materials

Motivation

This proprety request is part of the project of creating an infobox for materials.

Discussion

This is once again a proprety with lots of different testing methods. This mean that printing several values on infoboxes is usefull. -- Thibdx (talk) 11:15, 17 July 2018 (UTC)
