DELAYED YIELDING OF THREE-PHASE EPOXY COMPOSITES

A THREE-PHASE PARTICULATE COMPOSITE, CONSISTING OF FILLER AND VOIDS WITHIN A MATRIX WAS TESTED IN COMPRESSION UP TO YIELD UNDER SEVERAL CONSTANT STRAIN RATES. THE VOLUMETRIC FILLER AND VOID CONTENT RANGES TO 39% AND 52%, RESPECTIVELY, AND THE STRAIN RATES WERE WITHIN THREE DECADES. THE RESULTS YIELD A LINEAR RELATIONSHIP BETWEEN YIELD STRESS AND LOG STRAIN RATE OVER THE RANGE OF FILLER AND VOID CONTENT CONSIDERED IN THE THREE-PHASE SYSTEM. A RELATIONSHIP IS PRESENTED FOR THE YIELD STRESS OF THE THREE-PHASE SYSTEM AS A FUNCTION OF FILLER AND VOID CONTENT AND STRAIN RATE. THE SUGGESTED APPROACH USES RESULTS FROM A PREVIOUS STUDY CONCERNING THE YIELDING OF TWO PHASE FILLED AND POROUS COMPOSITES. /ASCE/
