摘要

This article introduced respectively the equivalent structural stress method which is based on the American ASME standard and the Miner cumulative fatigue damage theory. The Miner theory uses the S-N curve of welded joints provided in the IIW standard. These two methods are applied to the specific engineering cases of the aluminum alloy car body. The comparison shows that the equivalent structural stress method should be popularized widely.
