stress decay distance for seal groove
stress decay distance for seal groove
(OP)
I have a thick wall, steel shell (cylinder) with two internal seal grooves. These grooves are stress risers. Now the literature specifies a stress decay distance of k x square root of (R x t) for various types of discontinuities. The value of k used varies from Pi/2 to Pi/4 to 1.0 to 0.5 and sometimes 1.1. How does one select the appropriate value for k ? I presume that it depends on the type of stress, but so far, I haven't been able to see a pattern. Can anyone help with this?

If you need to know, you gotta test it.

I'm assuming this is a fatigue problem, not statics.
