Experimental variation in crack growth parameters introduces an uncertainty in the predicted minimum lifetime after proof testing that results in a possibility of failure at times less than the “minimum” lifetime. This failure probability is estimated with a Monte carlo simulation technique. A A example is given of how this failure probability can be made vanishingly small by increasing the proof stress or by decreasing the allowable stress or permissible lifetime in service.
