ABSTRACT
The shape of specimen is T-joint and dimensions of the specimen are shown in Figure 1. And the material of the specimen was AH32 steel plate and its mechanical properties are listed in Table 1.
2.2 Fatigue test condition
All test specimens were conducted in a servo-hydraulic, closed-loop mechanical test machine with 500 kN load capacity, which was interfaced to a computer for machine control and data acquisition. Also all experiments were performed based on storm loading proposed by Tomita et al. (1995), in air and at room temperature. Figure 2 shows the time history of storm loading applied to the specimen.
