Optimum Fillet or Draft
Optimum Fillet or Draft
(OP)
Folks
We need to apply a static 1000lbs tensile load to a step bar but my concern is necking rupture. Material is Steel 4130. Is there a formula to estimate the optimum fillet radius to use? or whether a draft taper will work better? If not, a FEA software like Creo structure will work as well??

I would have thought the the best fillet radius is the biggest one possible.

Lowest stress? Lowest cost? Lowest weight? Least material removed? Most difficult to machine?

What's the cyclical rate of loading?
