## Abstract Relaxation and stressβstrain behavior of SANβglass bead composites are studied above the glass transition temperature. The strain imposed on the polymeric matrix of the composite is defined as Ο΅~__p__~ = Ο΅~__c__~/(1 β Ο^β ^). Stress relaxation data for the filled polymer which is indepen
The magnitude of the activation energy for diffusion, ED. is shown to be inversely dependent on the fractional free volume of the polymer above Tg. From the proportionality of ED above and below Tg, the magnitude of El, below T, is also inversely dependent on the free volume in that temperature rang
The tensile behavior of polycarbonate was studied at large strains below the glass-transition temperature. Experiments were carried out at a series of constant temperatures and also under conditions of falling temperatures. The specimens necked with a natural draw ratio of approximately 2, and the s
