I'm trying to validate an FE model that I'm using by comparing to a simplified analytical solution to the problem.
The part I'm analyzing is a lug that is constrained on one end and has a point load on the other end. My idea is to model it as a stepped cantilever beam with either two or three steps then find the deflection using castigliano's second theorem.
What would be the most accurate way of modelling the deflection at the tip? What cross section sizes should I use for the different steps of the beam?
