Portland cement concrete is characterized by strain softening and nonlinear behavior. It has been shown that the nonlinear behavior of concrete is related to its heterogeneity; the larger the grain size and the larger the volume fraction of inclusions, the more nonlinear and tougher is the observed behavior. An alternate approach is to modify the concepts of linear elastic fracture mechanics to include the effects of slow crack growth and crack-tip nonlinearity (process zone) in analyzing the results of fracture toughness tests. This is attempted in this chapter.
