Hello all,
I´m kind of shy about posting this obvious 'beginner's question' about finite element method formulation, but I'd be extremely grateful if someone could take the time to maybe help me.
The problem I´m trying to understand is a bar with a non-uniform cross-section (E.A(x) = (EA0/2).(2 - x/L)
and is subject to a uniformly distributed axial load f. I would like to solve this problem with both 1 and 2 elements.
The differential equation for the problem is: d²u/dx² + f = 0, with the boundary conditions u(0) = du/dx (0) = 0 .
I have already solved for the analytical solution, and I would like the finite element solution with 1 and 2 elements.
Can anybody help me out?
