Originally proposed at Wikidata:Property proposal/Natural science
| Description | Material proprety measuring the ability of a material to absorb energy and plastically deform without fracturing. |
|---|---|
| Represents | material (Q214609) > mechanical property (Q5725005) > toughness (Q486802) |
| Data type | Quantity |
| Template parameter | This proprety request is part of the project of creating an infobox for materials |
| Domain | Mechanical property of all solid Materials |
| Allowed values | Any 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), under pressure (P2077), determination method (P459), Moisture absorbtion. |
| Allowed units | KJ/m3, J/m3, KJ/m2, J/m2, J/m, J/cm, J, ft-lb, ft-lb/in... |
| Example 1 | SAE 316L stainless steel (Q28453931) → 325 J / 76 ft-lb determination method (P459) → Charpy V-notch, temperature (P2076) → 30ºC under pressure (P2077) → 1 bar [1] |
| Example 2 | nylon 66 (Q7071155) → 0.267 to 7.47 J/cm / 0.500 - 14.0 ft-lb/in determination method (P459) → Izod Impact, Notched, temperature (P2076) → 23ºC under pressure (P2077) → 1 bar [2] |
| Example 3 | nylon 66 (Q7071155) → 0.0612 - 5340 J/cm / 0.115 - 10000 ft-lb/in determination method (P459) → Izod Impact, Unnotched, temperature (P2076) → 23ºC under pressure (P2077) → 1 bar [3] |
| Example 4 | nylon 66 (Q7071155) → 3.00 kJ/m² / 1.43 ft-lb/in² determination method (P459) → Izod Impact, Notched (ISO), temperature (P2076) → 23ºC under pressure (P2077) → 1 bar [4] |
| Example 5 | nylon 66 (Q7071155) → 60.0 kJ/m² / 28.6 ft-lb/in² determination method (P459) → Izod Impact, Unnotched (ISO), temperature (P2076) → 23ºC under pressure (P2077) → 1 bar [5] |
| Example 6 | nylon 66 (Q7071155) → 4.50 J/cm² / 21.4 ft-lb/in² determination method (P459) → Charpy Impact Unnotched, temperature (P2076) → 23ºC under pressure (P2077) → 1 bar [6] |
| Example 7 | nylon 66 (Q7071155) → 0.300 J/cm² / 1.43 ft-lb/in² determination method (P459) → Charpy Impact, Notched, temperature (P2076) → 23ºC under pressure (P2077) → 1 bar [7] |

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)
