Dynamics of Discretized Linear Systems
Discretization of continuos systems as by the finite element (FE) method is here restricted to linear systems. The main focus is on mass matrices, damping matrices and stiffness matrices and on a linear eigenvalue problems. Derived knowledge on real, positive eigenvalues, on mutual orthogonal eigenvalues and on mode expansion for general linear systems. Finally vibrations with single degree of freedom (dof) give introductory information on the influence from damping.
