fatigue strength of vascomax 350

araanandv2

Hi,

I need to calculate the fatigue strength of vascomax 350 material.
I have referred Machine design Hand book, Author-Shigley
The data provided and example calculation is for material having Ultimate strength less than 200ksi.
The Ultimate strength of vascomax 350 is 350ksi .

Please help me calculating the fatigue strength for the material.

Mainly I require the true stress at fracture (σ'F) for the material.

Thanks,

Ana
