SPECIFIC DAMPING CAPACITY AND COMPLEX MODULI OF VISCOELASTIC ORTHOTROPIC MATERIALS

The main purpose of the present paper is to calculate the apecific damping capacity (SDC) of a structure based on the complex moduli and compliances of its material under given harmonic loads and boundary conditions.Firstly,a three-dimensional viscoelastic analysis of complex duli and compliances of orthotropic materials leads to Eds. (23) (24),which express SDC in terms of complex moduli and compliances of the material.
