Z. R. Lu , J. K. Liu , M. Huang
Abstract
Vibration mode localization and frequency loci veering in disordered coupled beam system are studied in this paper using finite element analysis. Two beams coupled with transverse and rotational springs are examined. Small disorders in the physical parameters such as Young
Key Words
