The infinite strength module

class pylife.strength.infinite.InfiniteSecurityAccessor(pandas_obj)

Compute Security factor for infinite cyclic stress.

factors(woehler_data, allowed_failure_probability)

compute security factor between strength and existing stress.

Parameters:

• woehler_data (dict) – strength_inf: double - value for the allowed infinite cyclic strength strength_scatter: double - scattering of strength
• allowed_failure_probability (double) – Failure Probability we allow

Returns:

quotient of strength and existing stress

Return type:

double
