do a literature search at <http://www.scirus.com/> This topic has been beaten bloody over the last 50 years or so. The real problem is that there are no closed form solutions, and the effects of external loads are difficult to assess. Somewhere stress intensification factors are published for pressure loading on miter joints--values are somewhere between 2 and 3

If you're hell-bent on doing a miter joint for some reason, the quickest, cheapest way is FEA, particularly if you're carrying loads besides pressure.
