STRAIN GRADIENT AND THE STRESS-STRAIN RELATIONSHIP ON CONCRETE IN COMPRESSION
THE EFFECTS OF STRAIN GRADIENT ON THE STRESS-STRAIN RELATIONSHIP OF CONCRETE IN COMPRESSION, WHEN SUCH EFFECTS ARE NOT INFLUENCED BY THE PRESENCE OF A DIFFERENTIAL STRAIN RATE FOR DIFFERENT FIBERS OF A SECTION, ARE STUDIED. AN EXPERIMENTAL PROCEDURE IS DEVELOPED THAT PERMITS MAINTENANCE OF A CONSTANT STRAIN GRADIENT UNDER UNIFORM STRAIN RATES, MAKING IT POSSIBLE TO SEPARATE STRAIN RATE AND STRAIN GRADIENT EFFECTS. CONCRETE PRISMS ARE TESTED UNDER 3 DIFFERENT STRAIN GRADIENTS AND AT THE SAME UNIFORM RATE OF STRAINING. TEST RESULTS INDICATE THAT STRAIN GRADIENT, WHEN IT IS NOT ACCOMPANIED BY STRAIN RATE EFFECTS, HAS VERY LITTLE INFLUENCE ON THE STRESS-STRAIN CURVES OF CONCRETE IN COMPRESSION. /AUTHOR/
