Fatigue and the number of increments

Hi,

I don’t know what method you used for fatigue simulation. However, you can create multiple steps and divide the increments between the steps.

Check the link below. You might find something useful in it.

Another recommendation is to write a subroutine (UMAT or VUMAT). You can define the number of cycles you need, define several increments, and assign the cycles to the increments. For example, you have 100 million cycles; then, define 100 increments and assign every 1 million cycles to one increment.

Something like this is done on a composite model in the package that I sent you its link:

Best wishes.
