For linear discrete non-classically damped systems, it is shown that truncated orthonormal and biorthonormal eigenvector matrices can be developed for the purpose of uncoupling the physical equations of motion in a truncated ordered set of normal co-ordinates. This approach avoids for large systems
Finite element discretisations of higher order, applied to unsteady equations, generate nodal equations of unequal form. The stability analysis of a time-discretisation scheme for this system, by the local modal approach, therefore cannot be used. In this paper it is shown how, at the expense of a l
