flange plate question
i have need for a reliable way to check the stresses in a circular bolt pattern on a circular flange plate that joins two vertical shafts together. is there some software out there that can give me the max bolt tension and plate thickness required?  
i know the ultra conservative way would be to use a p/a + m/s method with pretensioned bolts, but when you encounter very high loads you just can't put enough bolts in place to accomplish this.  any help would be appreciated.

try
is this for a torsion or normal load?

thanx for mentioning the sites, but neither has any software that will do the job.

the connection is subjected to it all ---- moment, shear, axial and torsion.
i appreciate your interest in this problem.
