Damping of Particle-Reinforced Composites Due to Interfacial Sliding

Damping of Particle-Reinforced Composites Due to Interfacial Sliding Abstract Mechanical damping of composites reinforced by randomly distributed particles due to interfacial sliding is analyzed. The matrix is elastically isotropic, and the particles are assumed rigid and of identical radii. An auxiliary problem is solved at first for the steady-state response of an infinite matrix containing a single inclusion to a harmonic external load. The result is then used to derive the explicit expression of the specific damping capability of the composite by using Mori–Tanaka’s mean-field method. Numerical results are given and discussed in detail. It is concluded that the overall damping of the composite depends on several factors, including volume fraction of particles, Poisson’s ratio of matrix and a dimensionless parameter that incorporates the combined effects of particle size, matrix stiffness, interfacial viscosity and vibration frequency. The result is expected to be helpful in tailoring the damping performance of particle-reinforced composites. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png "Acta Mechanica Solida Sinica" Springer Journals

Abstract

Abstract Mechanical damping of composites reinforced by randomly distributed particles due to interfacial sliding is analyzed. The matrix is elastically isotropic, and the particles are assumed rigid and of identical radii. An auxiliary problem is solved at first for the steady-state response of an infinite matrix containing a single inclusion to a harmonic external load. The result is then used to derive the explicit expression of the specific damping capability of the composite by using Mori–Tanaka’s mean-field method. Numerical results are given and discussed in detail. It is concluded that the overall damping of the composite depends on several factors, including volume fraction of particles, Poisson’s ratio of matrix and a dimensionless parameter that incorporates the combined effects of particle size, matrix stiffness, interfacial viscosity and vibration frequency. The result is expected to be helpful in tailoring the damping performance of particle-reinforced composites.
