Abstract:

A deterministic mixture theory is presented for periodic particulate composites. The model is constructed by introducing convenient microdisplacment and microstress variables and by using a regular asymptotic technique with multiple scales. Governing equations and appropriate bounary conditions are then deduced from Ressiners mixed variational principle 1950. In order to test the accuracy of the present model, harmonic wave propagation is examined and compared with available experimental data for GlassEpoxy and SteelPMMA composites reported by Kinra and Ker 1983. Also, the effective elastic moduli are computed, and the results compared with other analytical methods. Keywords Wave dispersion.
