Evaluation of the Limit State and Cyclic Life of Structural Materials under Thermal Fatigue

摘要

The relationship between the cyclic life and reduced stress in half-cycles of heating (compression) has been established as well as the parameters defining the transition from the quasi-static to fatigue fracture mode and their threshold values. An approach has been proposed for the evaluation of cyclic life under thermal fatigue, which involves a preliminary prediction of the fracture mode and the use of calculation relationships corresponding to the predicted mode of fracture.
