This research will continue and complete the innovative experimental            fracture mechanics research in concrete.  The investigations to date            have shown that consistent non-linear fracture mechanics concepts can           be developed for concrete for differents modes of loading, (under Mode          I and II loadings).  The major objective of this continuation research          is to verify these predictive methodologies for discrete crack growth           in concrete.  This research will have analytical and experimental               components.  The experimental component will involve both fracture              process zone control studies using Mode I and Mode II type loadings,            and concrete beam studies for flexural and diagonal tension test on             crack propagation.  Numerical analyses studies will be carried out to           verify the experimental results.  The Kr values obtained using the              formula contained in ASTM 561-81 will be re-evaluated using a process           zone model.  The final numerical model will include the effects of              aggregate interlock and normal and shear stress interactions.
