| Abstract: | The method of spliting rigidity is applied.to predict the natural frequencies and modal loss factors ofviscoelastic damped sandwich beam,and simple and practical approximate formulae are presented. Based on theformulae,the expression of optimum shear parameter,which yieids maximum loss factor, is also derived for im-portant boundary conditions. |
