Precision of output valuesSet the required precision of the output fields with these two options: Conversion for stress intensity factorsSet both units and the input value on the left hand side. Conversion for Paris / Walker equation "C" coefficientSet all four units and the input values of C and n where da/dN=C(DK)n or da/dN=C[(DK)(1-R)(m-1)]n. Conversion for length unitsSet both units and the input value on the left hand side. Conversion for pressure / stress unitsSet both units and the input value on the left hand side. It is the responsibility of all users to verify conversions independently. Please inform us of any errors . |

Unit Conversions
The units used in a Zencrack analysis must be consistent throughout the analysis. This may require that reference data be converted between unit systems.
The most common error in terms of unit conversions relates to the crack growth law. References may not always be as clear as they could be in defining the units when stating the crack growth law C coefficient for Paris and more complex laws.
As well as providing some relevant standard conversions, the tool on this page can be used to confirm conversion of the crack growth law C coefficient for various units of da/dn and deltaK.
