| Abstract: | A method breaking a real variable amplitude loading applied to pressure vessels down into a load - spectrum of constant amplitude blocks is called ＂cycle counting method＂. The rainflow cycle count- ing method and max - min cycle counting method recommended both by ASME Code as well as the reservoir method recommended by EN Standard are introduced in this paper. |
