This isn't too tricky. Have a look at this link.. Lecture notes
Scroll down to the relevant section, which will depend on the orientation of your angles. There are expressions for beams in bending, cantilevers or tension/compression members. Assuming you know basic integration, you can equate...
Unfortunately, there is no "easy" solution as the plate resilience or stiffness depends on many influencing factors. The criticality of the joint will determine how far you go in terms of analysis and if critical I would suggest an FE analysis and/or testing of a prototype making use of strain...
One more thing to mention. If you're wanting to calculate off centre tensile forces you'll need to calculate the moment induced by said force to use with the software above. To do this you'll need to find the neutral axis in both x and y directions. For bolt groups this can be considered the...
The application of the elastic method is similar for bolt groups in torsion and bending, both require the neutral axis to be found initially. However, the moment of inertia calculations are slightly different.
This method, whilst easy to calculate, is conservative. The principal of...
