摘要：
The application of small punch test (SPT) for predicting the axial fatigue life of 304 stainless steel is examined. The results of SPT on predamaged 304 stainless steel sheets show that the increase in fatigue damage decreases the maximum punch load. However, the change in the maximum punch load can be translated into the change in the ultimate strength of the specimen according to the literature. Using the Palmgren–Miner model then, a cyclic load history is estimated that is found to be in good agreement with the actual loading. Consequently, the SPT is suggested as a fatigue life estimating technique where the past loading history is not available. In other words, this study proposes an SPT-based assessment of the remaining fatigue life of used components.
