Abstract:

The effects of temperature, strain rate and filler content on tensile properties of glass beadstyrene-acrylonitrile composites are studied. A point of discontinuity on the stress-strain curves for unannealed composites is investigated. Annealing results in smooth curves with no break points. A simple model for the filler effect on yield stress is suggested and shown to be in a good agreement with experimental data. A double shifting procedure to account for the temperature and filler effects on yield stress as a function of strain rate is proposed.
