Dynamic condensation techniques have been broadly applied to the domains of testanalysis-model correlation, vibration control, damage detection and so on to reduce the structural matrices (sti!ness, mass and/or damping matrices) of "nite element models. Based on the subspace iteration method in the
Based on the dynamic equations of equilibrium defined in the displacement space and the state space, two groups of iterative schemes for the dynamic condensation of nonclassically damped systems are presented. In the approach defined in the displacement space, the effect of the damping on the dynami
An efficient, iterative semi-implicit (SI) numerical method for the time integration of stiff wave systems is presented. Physics-based assumptions are used to derive a convergent iterative formulation of the SI scheme which enables the monitoring and control of the error introduced by the SI operato
## Abstract An iterative solution process combined with the penalty function method employed in constrained variational priciples is described. As an example of the use of the method an axiβsymmetric plate with the complementary energy formulation is considered.
