## 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 glass transition can be measured at different experimental conditions. Using spectroscopic methods at relative high frequency the a-relaxation is measured in the thermodynamic equilibrium. In the caloric case we call this phenomenon thermal relaxation transition (TRT). With a conventional differ
