Abstract
The simplified model test (SMT) method is an alternate approach to determine the cyclic life at elevated temperature. It is based on the use of creep-fatigue hold time test data from test specimens with elastic follow-up conservatively designed to bound the response of general structural components. In this paper, the previously documented development of the SMT approach and applicable restrictions are reviewed; the design of the Alloy 617 SMT specimen, measurement issues and constraints are presented; initial test results and their application to a prototypic design curve are presented; and further testing and analysis for ASME code incorporation are discussed.
