Stress - Strength Interference for two Normal Distributions Given the probability distributions for stress and strength, this module will find the probability of failure due to stress-strength interference. Failure is defined as when stress>strength. Uses the exact formula method which is only valid for two Normal Distributions.

Inputs: stress - a probability distribution from the Distributions module strength - a probability distribution from the Distributions module show_distribution_plot - True/False (default is True) print_results - True/False (default is True) warn - a warning will be issued if the stress.mean > strength.mean as the user may have assigned the distributions to the wrong variables. You can supress this using warn=False

Returns: the probability of failure
