EVALUATION OF THE FRACTURE BEHAVIOR OF CONCRETE WITH THE J-INTEGRAL

This report seeks to determine if the J-integral concept is applicable to concrete fracture mechanics. The J-integral is a path-independent line integral that is a measure of the elasto-plastic stress-strain field near a crack tip. Various experimental factors were evaluated in order to ascertain which ones significantly affect the performance of the J-integral as a one-parameter measure of fracture toughness. In addition, the critical value of the J-integral (JC) was compared with other fracture toughness parameters. Correlations drawn from these comparisons provide further insights into the realistic usefulness of the J-integral.
