PBEAM fatigue analysis

Recommended Posts

I'm trying to make a fatigue analysis of a chassis. I meshed the chassis by 1D line mesh with PBEAM property.


On FATDEF I put the option PBEAM in PTYPE area and when I try to analysis was showed the follow message:

 *** ERROR # 6817 ***
 PBAR/PWELD only can be used for spot weld fatigue analysis. PFATSPW 
 is required for spot weld fatigue property. 
            FATDEF ID = 9 
        PBAR/PWELD ID = 3 
              PFAT ID = 8.


How I complete my fatigue analysis of my 1D elements?
