 # creep_failure_time¶

class reliability.PoF.creep_failure_time

This function uses the Larson-Miller relation to find the time to failure due to creep. The method uses a known failure time (time_low) at a lower failure temperature (temp_low) to find the unknown failure time at the higher temperature (temp_high). This relation requires the input temperatures in Fahrenheit. To convert Celsius to Fahrenheit use F = C*(9/5)+32 Note that the conversion between Fahrenheit and Rankine used in this calculation is R = F+459.67 For more information see Wikipedia: https://en.wikipedia.org/wiki/Larson%E2%80%93Miller_relation

Inputs: temp_low - temperature (in degrees Fahrenheit) where the time_low is known temp_high - temperature (in degrees Fahrenheit) which time_high is unknown and will be found by this function time_low - time to failure at temp_low C - creep constant (default is 20). Typically 20-22 for metals print_results - True/False

Outputs: The time to failure at the higher temperature. If print_results is True, the output will also be printed to the console.
