| Symbol | σFlimN |
|---|---|
| Unit | N/mm² |

| Value Type | PMTechValue |
When "Acc. to VDI 2736:2014" is selected, σFlimN is determined from the tooth root temperature and the number of load cycles for selected materials:
| Material designation | Calculated from the equations in VDI 2736 for |
| POM | POM |
| PA66 | PA66 |
| PET | PET with oil lubrication |
| PEHMW | PA 6 - grease lubrication |
| PBT | High molecular weight PE with water-oil emulsion lubrication |
| Laminates | Coated press materials (Hgw) |
To ensure that the internal calculation for the material is correctly controlled, the material designation must correspond exactly to the value in the above table.
When "from measurement data" is selected, σFlimN is determined using the specified measurement data and the existing number of load cycles.
When "from material" is selected, the value for σFlimN for the material is used.
