A New Model Updating Method for Quadratic Eigenvalue Problems

In this paper, we consider two finite ele- ment model updating problem which incorporate the measured modal data into the analytical finite ele- ment model, producing an adjusted model on the damping and stiffness, that closely match the experi- mental modal data. We develop an efficient numerical algorithm for solving this problem. The new algo- rithm is direct methods which require O(nk 2 ) flops.
