Fatigue Analysis in Ansys Workbench Environment

Hello everybody

I’m trying to do a fatigue analysis with Workbench Ansys. The load exerted on model in 2.7 seconds and varies between two values (it increases, reaches to a peak and then decreases to first value) and these 2.7 s cycles continue to failure. I was wondering if it’s possible to model this load history in Workbench environment. Also if possible, please tell me how to do that.( load graph attached)

Thanks in Advance
