PhD Robust Optimization Viscoelastic Sandwiches
Visco-elastic structures are widely employed for vibration damping. Nowadays, optimal design of these structures has become commonplace. However, operating conditions introduce variability in their performances. Taking into account this variability in the optimization loop is necessary to obtain optimal robust solutions. Recently, within an exploratory project, supported by CNRS, the modal stability method (MSP) has been applied with success to quantify variability of damping and natural frequency of frequency dependent viscoelastic sandwich structures.
