| Abstract | Reduction methods are used to reduce the number of degrees of freedom in a finite-element (FE) model at the expense of high-fidelity solutions. The System Equivalent Reduction/Expansion Process (SEREP) is an attractive reduction technique since it can preserve the modal fidelity of the FE model up to a user-defined level. This capability allow for a more accurate representation of the physical structure. In this report, the feasibility of incorporating SEREP in the FE method for both discrete spring-mass-damper and distributed systems is explored. Modeling and numerical issues related to using SEREP as a superelement technique are examined and discussed. |
