Method censored samples consideration in composite fatigue testing

Abstract

Summary Taking into consideration the huge scatter of fatigue performance of composite, as well as the experimentally proved absence of unconditional fatigue limit, the method for statistical improvement was developed which allows to improve the statistical quality of fatigue curve. Some preliminary considerations about mechanical testing tool in quality control are shown. The source of data scatter in fatigue testing is discussed. For building of the method, the statistical approach from the group of intensive use of computer, namely, bootstrap was employed. The model example on the base of real testing was investigated. Applying the method will help to include the information of censored samples into the result of testing.
