Stress Concentration Calculation

Hi everyone,

I wanted to know the stress concentration factor (Kt) for a cantilever beam with a fillet at the root with a point load applied at the end. Can I get the stress concentration factor if this beam is a 3D beam (thickness is comparable to length)?
I had a look at Peterson's SCF handbook but this particular geometry is i guess complex to be not listed.
Thanks

Do you mean that the depth of the beam is comparable to its length?

Thickness is the beam width, into the page.

Can I get the stress concentration factor if this beam is a 3D beam (thickness is comparable to length)?
koolraj09: Yes, you could get an approximation, especially if the tip load is consistently applied, per unit width into the page, along the tip of the cantilever.

See the attached figure. It probably comes from Peterson's, or similar. Let us know if the figure is unclear.
