Description/Abstract Progress is reported on (1) interpretation of interface tests; (2) the effect of interface properties on flexural strength and its connection with uniaxial tensile strength, and (3) effect of interface properties on uniaxial tensile strength. Goal is to establish relations between manipulable material variables and mechanical response. The approach has been: (i) to hypothesize as to the key underlying physical mechanisms and to represent these hypotheses with model theoretical problems which can relate material parameters to observed mechanical behavior, (ii) to develop the necessary techniques to analyze the model problems; and (iii) to test the models by comparing the obtained results with experimental data. Phases 1 and 2 have been brought to satisfactory completion; work remains to be done on the third phase.
