Abstract
Typically, the conventional finite element method (CFEM) for rotating beams uses cubic polynomials as interpolating functions and convergence is achieved by increasing the number of elements. Since dynamic analysis requires at least the first five modes, capturing these modes accurately requires many elements which leads to a large size eigenvalue problem.
