Can we define material property in Tabled Type of Fatigue?

Recommended Posts

I know we can set material property of fatigue in MATFAT.

 

And we can set the SN curve points of the material.

 

I am curious about can we use the TABLE's type to import our material data in fatigue material?

 

Because at the thermal we can do for this.

And I also have problem about the FATPARM's instruction of COMBINE

 

what is "SG" mean?  Because I have seen it shown like the photo and it also written in SGVON (SG von-Mises)

hi,

 

Do you mean non-linear material?

 

Von Mises alone is strictly positive. So, if you are referring Vonmises for fatigue analysis only positive history is taken into account. Whereas signed-von Mises can take both negative and positive. Same with Tresca
