System and method for determining direct damage tolerance allowables
A method of determining damage tolerance allowables in a specimen, the method includes applying a cyclic load to a specimen until a first crack emanates from a notch in the specimen, the cyclic load having a maximum load and a minimum load. The method also includes applying a subsequent cyclic load to the specimen until the first crack grows to form a second crack emanating from the first crack, the subsequent cyclic load having the same maximum load but a greater minimum load.
