Hey guys, I have a question regarding allowable stress
Thread Content
According to Table 2 of GB150.2, how can the allowable stress for Q245R at a design temperature of 330 degrees and a thickness of 12 mm be determined? The table only provides the allowable stresses at 300 degrees and 350 degrees. . .
Just use the insertion method for calculation, or enter the values directly for the software to generate them automatically. 102
Bro, can you talk about interpolation? .
Insertion method: 300 and 350 don’t work; 108 and 98 also don’t work. 108 – 98 = 10, and 350 – 300 = 50. 10 ÷ 50 = 0.2. 330 – 300 = 30, and 0.2 × 30 = 6. 108 – 6 = 102. Strength calculation software: RV or SW6
Using CAESAR II software, the allowable stress is displayed as soon as it is entered
The SW6 software can also be displayed directly.
The difference is not significant; it is possible to consider designing it at 350 degrees
