Influencing factor for the permissible tooth root stress

By means of the user-specific influencing factors Y₁ to Y₅, additional Y-factors can be specified to determine the permissible tooth root stress according to the ISO 10300 (2014). Several factors are available, so that different influences (e.g.: hardening depth, shot peening) can also be taken into account in different factors when determining the tooth root load capacity. These factors are multiplied by the permissible tooth root stress when determining the safety factor. Values greater than one thus increase the calculated safety factor. These Y-factors are set to 1.0 by default.
