Reduction method applied to vibrations of viscoelastic sandwich shells

Résumé

This work deals with the vibrations of sandwich visco-elastic structures. The central visco-elastic layer included between two metallic layers leads to solve a problem of complex and non-linear eigenvalues. Indeed the core material depends on the frequency. Several methods exist to solve this type of problem. But the dimension of matrices to be manipulated can become very large and generate substantial computational times. A reduction technique is proposed herein. It is applied and compared to the high order Newton method.
