ASME VIII 2004 Part UHX Tubesheet
(OP)
I have been doing calculations on tubesheets using UHX-13. I am using a excel spreadsheet and am looking for excel formulae for the Bessel functions (actually Kelvin functions) [b]ber(x)[b] and [b]bei(x)[b]and their derivatives. Can anyone help - I can only find the BesselY(x,n) and BesselJ(x,n) functions. What is the relationship between ber(x)/bei(x) and BesselY/BesselJ??
