Dynamic Fracture of Concrete and Other Heterogeneous Materials.
Abstract
Damage in concrete is characterized by microcracking and/or the development of large cracks. In this study, the physics underlying the relationships between microcracks and damage and the implications of these factors on the mathematical modeling of engineering structures have been studied. Particular issues which have been emphasized are: (1) the size effects on brittle failure, (2) shear fracture and (3) the mathematical and phenomenological consistency of strain-softening models with damage processes in concrete. The effect of the size of a concrete structure on the nominal stress at brittle failure is studied by dimension analysis and illustrative examples.
