内容記述 | A numerical method is proposed to calculate damping properties for sound-proof structures involving solid body, porous media and air in two dimensional regions. Both effective density and bulk modulus have complex quantities to represent damped sound fields in the porous media. Particle displacements in the media are discretised using finite element method. For solid body, displacements are modeled using conventional finite elements including complex modulus of elasticity. Displacement vectors at common unknown varriables, are solved under coupled condition between solid body, porous media and air. Further, explicit expressions of modal loss factor for the mixed structures are derived using asymptotic method. The proposed methods yield appropriate results for some sample problems. Moreover, it is found that damping can be coupled in the mixed structures. | |||||
