(OP)
Does anybody use the Nelson Stud method for designing embeds, i.e., number, size and spacing of studs? The plate thickness is designed
by standard engineering mechanics.

For studs (at this point) I use Appendix D of ACI 318. (There was a time when I would use the methods in the PCI handbook, but they appear to be unconservative compared to Appendix D in the calculations I have done.)
For embedded plates, as far as the concrete pullout strength goes, I just use the normal two-way/one-way failure planes that ACI 318 gives the strength for.

I assume everyone knows what a Nelson shear stud is.

My typical situation is a flush mounted plate.

I don’t think it is. I don’t think they did the extensive testing that was performed to develop Appendix D. You look at the various failure modes that Appendix D considers and then consider the fact that some of those older methods don’t even touch them……and you then realize which one you should be using. The bottom line is: You can defend using Appendix D in a court room…..so getting away from that is risky.
