Experimental Study on Fatigue Characteristics of Structural Steel Part 2: Cyclic Deformation Capacity of Structural Steel SS400 under Large Strain Amplitude

摘要

In this study, cyclic loading tests of 400 N/mm~2 class structuralsteel (SS400) under large strain amplitudes up to 12%, which coverboth low cycle and extremely low cycle fatigue regimes, wereconducted. Also, relationship between strain amplitudes and numberof cycles to complete fracture as well as peak stress were alsodiscussed. The overall conclusions in this paper can be drawn asfollows.
