Evaluation of visco-elastic sandwich beam damping and natural frequency variability using a modal stability procedure

Résumé

The modal stability procedure is used along with Monte-Carlo simulation to quantify the variability of frequency and damping ratios of a rectangular three-layered simply supported sandwich visco-elastic beam. The asymptotic numerical method is used to compute the complex eigenfrequencies at nominal in the case of a high damping frequency dependent material (3M ISD112). The results are compared with analytical data.
