Design Optimization Utilizing Dynamic Substructuring and Artificial Intelligence Techniques [PDF]

, 2008
In mechanical and structural systems, resonance may cause large strains and stresses which can lead to the failure of the system. Since it is often not possible to change the frequency content of the external load excitation, the phenomenon can only be ...
