Abstract

Computation of homogenized coefficients for a viscoelastic composite reinforced with spherical inclusions N. Labed*, F. Guillaumin* ^Polytechnic Institute of Sevenans, Laboratory of Moderation Structural Mechanics, rue du Chateau 90010 Belfort, France ^Laboratory of Modelisation and Mechanics of Structures, UPMC 4, place Jussieu 75252 Paris, France ABSTRACT The viscoelastic composites are being more widely used in the industry. While remaining light materials with good mechanical stiffness characteristics, the viscoelastic composite materials provide interesting absorption properties and can reduce the vibratory disturbances. The paper is concerned with the behaviour of a viscoelastic composite incorporating isotropic viscoelastic balls embedded in isotropic resin subjected to harmonic vibrations. The wavelength considered is large compared to one period of the medium, and therefore, the homogeneization of the medium is substantiated allow to replace the highly heterogene
