LIFETIME PREDICTION METHODS FOR ELEVATED TEMPERATURE FATIGUE

摘要

This paper reviews recently developed methods for metal lifetime prediction at elevated temperatures. These methods can be categorized as either (a) Parametric, (b) Damage Summation, (c) Strainrange Partitioning, or (d) Frequency Modification. The capabilities and limitations of these various approaches are discussed and the problem of extrapolation beyond laboratory experience is considered.
