(OP)
Anyone can help me find the frequecy formula for a spherical shell? Actually, it's just like a ball, supported by a skirt.
I can do a rough calc for the beam mode frequecy but not shell mode. Since there is no software and reference book, so need your help.
Thanks in advance,

Refer to the following book:
Robert Blevins, Formulas for Natural Frequency and Mode Shape.

It is becoming easier and cheaper to do a quick modal analysis of simple geometry like you are talking about. Although, if your geometry in question is a simple sphere, Blevins may help you.
