I want to plot eigen vectors and mode shapes of a Timoschenko beam. I already have solved the system using finite element methods and generated stiffness, mass and damping matrices.
I am attaching them as files. I calculated natural frequencies using this equation
de = sqrt(eigs(Stiffness_Global,Mass_Global,12,'smallestabs'))/((2*pi));
and the result I got is this:
Now, how can I calculate mode shapes of these frequencies and plot them..?
I tried using this equation
[V,D] = eigs(Stiffness_Global,Mass_Global,12,'smallestabs')
but the results, I cannot understand them
Does anyone know..?
