摘要: ABSTRACT A new finite element is formulated and used for the analysis of sandwich damped beams with laminate piezoelectric faces. The viscoelastic damping core accounted using three models, namely Golla-Hughes-McTavish, Anelastic Displacement Fields Iterative Modal Strain Energy. Since first two models increase much system dimension, a modal reduction proposed. reduced are then applied to active constrained layer treatments cantilever beam, input optimal control algorithm. Furthermore, effect temperature variations on performance studied
