摘要：
This paper describes the high temperature multiaxial creep-fatigue life prediction for type 304 stainless steel. Finite element analyses were performed for determining the stress-strain state in the gage part of a cruciform, specimen subjected to creep-fatigue loading under four strain waves at three principal strain ratios. Creep-fatigue lives of cruciform specimens were discussed in relation to the principal stress amplitude calculated by finite element analysis. Creep-fatigue damage was evaluated by linear damage rule and the suitability of three low cycle fatigue and three creep damage parameters was discussed. (C) 2007 Elsevier Ltd. All rights reserved.
