FRACTURE MODEL FOR FIBER REINFORCED CEMENTITIOUS MATERIALS

A STATISTICAL MODEL DEVELOPED TO PREDICT THE TENSILE PROPERTIES OF DISCONTINUOUS FIBER REINFORCED CEMENTITIOUS MATERIALS, WITH PARTICULAR EMPHASIS ON FIBER REINFORCED CONCRETE IS DESCRIBED. THE FIRST PART, SIMULATING DUCTILE FAILURE, IS BASED ON THE MECHANICS AND STATISTICS OF COMPOSITE MATERIALS. THE SECOND, COVERING BRITTLE FAILURE, INCORPORATES A FRACTURE MECHANICS CRITERION IN THE ANALYSIS. EACH FORMULATION LEADS ESSENTIALLY TO THE ASSESSMENT OF THE COMPOSITE CHARACTERISTIC TENSILE STRENGTH AND ITS DISTRIBUTION FUNCTIONS. THE CHAIN WEAKEST LINK CONCEPT OF RELIABILITY THEORY IS THEN APPLIED TO BOUND THE OVERALL MODEL AND PROVIDE RESULTS AS MODIFIED BY THE SIZE OF THE TENSILE MEMBER. /AUTHOR/
