FATIGUE ASSESSMENT

摘要

Methods are disclosed relating to the assessment of fatigue damage in objects that include for example, subjecting a fatigued object to a cyclic mechanical stress, measuring a rate of temperature rise in the fatigued object, and assessing a degree of fatigue of the fatigued object based on the rate of temperature rise in the fatigued object. Methods of measuring internal structural characteristics and methods of correlating fatigue damage to results from excitation tests are also taught.
