Equivalent stress amplitude is calculated by Good-man formula[5]: (1) (2) Where is amplitude of real-time stress signal, is limit of intensity of the material , is amplitude of static failure stress, is average stress value, is the amplitude of equivalent stress value, and 1.3 is dimension correction factor . 2.4 Calculations of the P-S-N curves of six Points According to JIS B 8821-2004 Fatigue properties of material generally represented by uniaxial stress - cycles :S-N curve(without considering fatigue theroy based on fracture mechanics).Material S-N curve is acquired by constant amplitude load test of standard sample under a specific stress cycle mode.
Each actual state of the structure (size, surface roughness, and welding) is different, we can not directly use the material S-N curve to estimate the fatigue life of structures, so it must be amended to component P-S-N curve which can be used to estimate structure life.
