Fatigue life analysis
Fatigue life analysis
(OP)
Hi,
I have been given a problem that involves the prediction of Fatigue life for a steel padeye...
I have already performed a dynamic analysis of the problem via Abaqus and the results are satisfactory.
My question is - how do I perform a Fatigue life analysis via Abaqus – if that makes sense...
All thoughts appreciated in advance...
Thanks

doing the same by means of hot spot stress, out of abaqus.
I just use abaqus to:
- get the internal forces during the dynamic situation
- calculate the hot spot SCF ina diferent model
with this i perform fatigue in excel
good luck![dazed]

I use the same technique as n3l3, then I treat the resulted field of stresses out of abaqus using software like excel or matlab. The right choice of fatigue criteria is what determines the precision of your calculation.
