FRACTURE MECHANICS - ITS APPLICABILITY TO CONCRETE

The applicability of linear-elastic fracture mechanics to Portland cement pastes, mortars, and concretes was determined by the fabrication, testing, and analysis of plate specimens containing a precast flaw. The results show that the concepts of linear-elastic fracture mechanics are not applicable to concrete materials. A rigid plastic cracked strip model was developed to provide an estimate of the microcracking zone that exists in the region of the crack tip in cement pastes, mortars, and concretes. The experimental results are correlated with the model. /AUTHOR/
