Fatigue analysis MATFAT parameters

Recommended Posts

@Prakash Pagadala @Rahul R

Hello Sir,

I have doubt regarding MATFAT parameters in opti.

Can you please tell me the SRI1, b1, Nc1, FL parameters values for following Material stress data:

Alternating Stress(Amplitude)     Life

4000 MPA                                    1

855 MPA                                      1000

86.2 MPA                                     1000000

 

86.2MPA is the fatigue strength/endurance strength of the material.

Please guide me to calculate the MATFAT parameters from given material data. I am confused about where to double the values for stress range and where not to. If you will elaborate with the given data it will help me a lot. Kindly reply at your earliest convenience.

Thanking you in anticipation.

 

Regards,

omkar Bhumkar
